What are the major cybersecurity challenges you see for the public sector?
In all businesses, a balance has to be struck between what the business needs, how much risk it can afford and the budget. The security budget globally is around 5% of IT budgets. Five percent is not a small amount. If directed properly it could be used to make the organisation reasonably secure.
A CIO in the private sector might get overly excited by the new, cool security start-up that they met last month at a convention and then spend money buying their product, without analysing if it works for them.
With governments, the problem is the opposite. They are very conservative. They want stable, reliable solutions, from big established names. That makes them buy legacy products, such as anti-virus and firewalls, which might not no longer be relevant and which drain dollars from that 5% IT security budget towards ineffective, out-of-date solutions.
Governments are relatively slow in responding and embracing new technology. They are often not pro-active. If one division gets targeted by ransomware today, tomorrow all the security dollars will go towards ransomware. You can bet that tomorrow the threat won’t be ransomware. By the time you deploy sandboxing technology to protect yourself from ransomware, you have to deal with something else.
Governments need to start thinking ahead of time and focus on not just patching the problems of today, but look to where we are going and prepare for those challenges.
Where are the threats coming from?
The problems are coming from inside, not outside. Insider threats are a daunting challenge.
It is not just malicious insiders. It could be insiders who just want to do the right thing for the company.
Say a nurse who needs to have the patient data on-hand, as she goes for rounds with the doctors. She just puts the data on an unsecured USB drive. You ban USB drives, she creates a Google drive account. She is putting patient data at risk
You need to have a technology that allows this lady to do business but also protects the company and the end-users, ensuring that the data stays safe.
Do you think most nations are considering the risks associated with IoT, when developing their Smart Nation plans?
During the Singapore International Cyber Week, the Prime Minister did not say Smart Nation. He said Secure Smart Nation.
That’s the problem with most other countries. Most countries end up saying something along the lines of, “We are going to embrace Smart Nation. Can you give me some boxes to make it secure?” That is not how it works.
The Singapore approach is a good one. In Singapore, new projects are going to be built with security in mind, which is fantastic.
These days everyone is talking about security-by-design. But what do you do about the systems and the infrastructure you already have in place?
Last month, we released a report on ‘Abandonware’. It is a term commonly used to refer to legacy game software that has been abandoned by the author but is still widely loved and used by the user community.
We have become accustomed to and rely upon various web-connected devices, available whenever and wherever we need them in our personal and professional lives. We expect them to receive the benefits of automatic patching and updating of software, as is done by Apple, Adobe, Microsoft and Google. We have become so used to it that this leads to a sense of complacency and we don’t bther to check for vulnerabilities while using "end-of-life'd” software, for which no product support is available.
Here we are using it to refer to the use of software that has come to its end-of-life but, for a variety of reasons, is still in use. We had a case study where around 75,000 users in the IT security field continued to use an abandoned and somewhat obscure plug-in for an abandoned software package, thereby unknowingly and unnecessarily putting themselves at risk.
In your view, what kind of approach should be taken by governments for defending their organisations against cyber-threats?
You might have a hundred pieces of security software, but still not be secure because you do not have access to the big picture. Instead you have thousands of logs. A disjointed view can hinder the ability to detect and defeat advanced security attacks.
We invested to connect the dots and produce a risk-incident scoring system. It will help in prioritising. It will tell you that these are the incidents you need to deal with first.
Having a security process, however robust it might be, cannot make anyone fully secure. We need to figure out what is the most important thing to protect. It is not the devices.
Protecting all devices in any organisation might be a lost battle. What I need to protect is the data. That’s where I should be investing 95% of my IT security budget.
We have to protect data contextually. Suppose you have a legitimate reason to access customer data on a regular basis. But if the security system detects that all the customer details are being sent out in a batch, that should be a red flag. Either you are doing something wrong, maliciously or otherwise and you need to be stopped or it is someone pretending to be you.
So, contextual, behavioural analysis is essential, around data, not around people and devices. In the past we protected laptops. Protecting the data is of paramount importance in today’s environment.
Indonesia’s Ministry of Communication and Informatics conducted a familiarisation workshop for health workers and non-medical staff about Electronic Medical Records (RME). According to Health Ministry regulations, health facilities in Indonesia are required to use RME. Indonesia Social Security Administrator (Health BPJS) now offers an integrated RME computing system. Some digitally based hospitals have used the system for RME.
“Through this workshop and seminar, the Ministry of Communication and Informatics introduces Electronic Medical Records (RME) so that participants can understand what RME is and how the supporting technology works,” said I Nyoman Adhiarna, Director of Digital Economy at the Ministry of Communication and Information.
Essentially, health facilities must use the electronic record for patient registration activities, clinical information filling, storage and transfer of medical records, ownership and contents of patient medical records, security, and data protection.
Meanwhile, Setiaji, the Chief of the Ministry of Health’s Digital Transformation Officer (CTO), emphasises the importance of information technology as the backbone of the ongoing transformation of the national health system. “One of the major agenda items is the implementation of electronic medical records, which has begun with the launch of the SATU SEHAT platform.” “This platform connects sixty thousand health services across Indonesia,” he said.
The seminar also covered several topics, such as the role of medical recorders and health information (PMIK) in the success of RME adoption, RME integration with cyber security, change management in RME adoption, and RME adoption and its implications for hospital services.
Director Nyoman acknowledged challenges in implementing RME in hospitals, such as internet network connectivity and cyber security. However, adequate digital infrastructure would make digital transformation in health care more accessible. As a result, the Ministry of Communication and Informatics is currently focusing on developing digital infrastructure in remote areas, known as the 3T acronyms for frontier, outermost, and lagging.
A multifunctional satellite, Satellite Indonesia Raya (SATRIA) 1, will provide support for remote internet access. The broadband satellite will launch in 2023 to reach 150,000 public service points.
As the health sector becomes increasingly digitalised, cyber and data security has become a significant concern. According to Director Nyoman, all PSEs, both public and private, that manage personal data are urged to pay close attention to the feasibility and dependability of personal processing data, particularly those related to technology, governance, and human resources.
He is also concerned about the role of the Data Protection Officer (DPO) following the implementation of the government’s data protection law. Each electronic system operator must legally have a person in charge of data protection.
“Later,” he said, “a Personal Data Protection Agency will be formed, which will most likely be under the Ministry of Communication and Informatics.”
Director Nyoman also emphasised the Ministry of Communication and Informatics’ role in assisting the Ministry of Health in becoming the leading sector in the health sector to accelerate digital transformation in the health sector.
The Ministry of Communication and Information welcomed the One Healthy Indonesia Health Service (IHS) platform, launched in July 2021 by the Ministry of Health as a digital transformation programme based on an integrated and standardised health data system.
Australia’s national science agency, CSIRO, recently revealed details of an AU$15 million project to develop a national soil information system, aimed at improving the sustainable management of one of the nation’s most precious assets.
Supporting the National Soil Strategy, and funded by the Australian Government’s Department of Agriculture, Fisheries and Forestry, the Australian National Soil Information System (ANSIS) project is a collaboration between the government, research organisations, industry, the private sector and the community.
Using innovative processes and technologies, ANSIS will allow improved sharing of nationally consistent soil data and information through online access for users. This will help Australians to better understand their nation’s diverse range of soils and make better decisions about managing our important soil resources. Currently, soil data is collected using different methods, by different organisations, and at a range of depths in the soil. This makes it hard to access, compare and use data from diverse sources.
The Project Lead at CSIRO stated that improving access to the best soil data and information can help promote digital agriculture innovation and is key to sustainably managing Australia’s soils. By using ANSIS, farmers and agricultural advisors will have access to more soil data and be better placed to more sustainably manage the soil on which they rely.
Soil is vital to agricultural production and natural environments, as well as health and well-being. This information system will help everyone care for this important natural resource. Productive, healthy, and resilient soil means more economic, environmental, and social benefits to Australia. Monitoring soil also helps scientific understanding of how the natural world is changing.
This work will provide insight into biodiversity, water resources, landscapes and coastlines, fauna, climate, and geology. By harmonising Australia’s soil data, we can make it accessible across many fields of science and exploration. The project is being delivered under the Federal Government’s National Soil Strategy, which is about prioritising soil health, empowering soil innovation and stewards, and strengthening soil knowledge and capability. The new ANSIS system will be available for use in 2023.
ANSIS will provide improved access to nationally consistent soil data and information needed to help sustainably manage Australian soil. ANSIS will provide:
- More soil data
- More data sets are available that in other soil systems
- Enables more certainty in products developed
- Opportunity to develop new products
- Improved access
- Multiple data sets are now discoverable and accessible
- National coverage
- Most up-to-date data available
- Efficient provision
- Organised and standardised data for immediate use
- Can feed into many users’ requirements
- Consistent delivery
- Substantial reduction in time to prepare information products
- Trusted location
- Certainty that data is from an authoritative source, verified and satisfies standards.
AI and other digital technologies could help solve some of the world’s most important social problems, like climate change, biodiversity loss, food insecurity and risks to public health, among others. Harnessing digital capabilities to promote a transformative system could be a game-changer for a sustainable and equitable global future.
Today’s consumers expect more than great products and services, and businesses are well aware of this. Clients want to feel like they are investing in a reputable, responsible brand. Consequently, the most market-dominant businesses are not merely profitable and have good products but those that have multiple alternate bottom lines – social, environmental and sustainable.
More than 90% of business executives agree that sustainability is crucial to their success. As consumer groups continue to publish reports on the increased desire for more environmentally friendly corporate practices, it is simple to see why green marketing strategies are gaining such importance.
The environment and sustainability are vital components in the strategy and operations of enterprises looking to be more conscientious. Organisations have been taking proactive steps to develop a greener future with their consumers, partners, stakeholders and workers. These efforts include environmental initiatives, community outreach efforts and business practices.
Advancing Environmental Sustainability and Resilience
“Everyone is becoming aware of the necessity for action to attain sustainability,” says Vivek. “There is a growing interest in corporate sustainability and how corporations can strive for it to meet the needs of stakeholders for social, economic, and environmental implications.”
Most businesses are considering ways to contribute significantly, which will need robust investment and efforts. “We see businesses quickening their momentum and considering effective climate innovations. A case in point is how electric mobility companies can be affected by the huge reductions in costs for climate technology.”
Vivek believes it is possible to adapt a company’s digital strategy to mitigate and deal with extreme climate change. Companies must include digitalisation and decarbonisation in their strategy, as industry 4.0 technologies will play a crucial role in meeting the emissions reduction goal.
Digital technologies can increase energy efficiency and decrease fuel consumption across multiple industries and sectors. Digitalisation has the potential to revolutionise the way people and technology interact by helping to analyse and calibrate necessary interventions.
By utilising digitalisation, businesses can identify the emissions sources, whether at the product level, manufacturing unit level, or equipment level. They can then determine the necessary interventions to reduce emissions, such as a change in the manufacturing or personnel settings, and then monitor whether the identified interventions are being implemented.
“Here is where I believe digitalisation and decarbonisation must go hand-in-hand, as this will ensure that industries undergo structural changes and reach their objective,” says Vivek.
Businesses need to be more conscious of the need to be prepared for the energy shift, and he has five relevant steps for how businesses should approach this:
- Develop an understanding of how energy shifts will affect your company;
- Think about a bold and ambitious target, such as considering how big of a carbon footprint reduction they intend to achieve with this energy transition;
- Consider various situations and their effects;
- Create a comprehensive plan that will serve as an overall strategy with well-defined and cascading targets;
- Think about implementation, where companies strike a balance between all the goals, e.g., carbon footprint and profitability
Right now, society is more conscious of sustainability and is calling for companies to shift their carbon footprint and be more conscious about emissions. This is causing profound changes in the corporate and government landscape.
Organisations can work toward more sustainable practices with the aid of corporate sustainability’s economic, social and environmental pillars. Businesses must alter their mindset from just profitability at the expense of the environment to a sustainable and profitable paradigm. There must be interdependence and a greater emphasis on operations and eco-innovation.
Adopting sustainable practices benefits the environment, but businesses have also demonstrated that these programmes can boost productivity, lower costs, make shareholders happy, and a host of other advantages.
“Corporate entities must take the initiative in determining pertinent technologies. Companies must implement technologies to decrease their carbon footprint. They are the ones that will bring about change. Governments can decide the legislation, but unless companies change, it will be difficult to achieve net zero,” Vivek firmly believes.
A green economy is the practice of sustainable development supported by public and private investment in creating an infrastructure that promotes social and environmental sustainability. A green economy refers to an economy in which individuals are increasingly aware of their carbon emissions and are taking steps to reduce them.
A carbon footprint is the total amount of greenhouse gases, including carbon dioxide and methane, that corporations and individuals generate.
There are numerous practical and effective approaches to implementing sustainable technologies at the national level. “I believe that each country will deploy different technologies; the mix of technologies, the adoption rate, and the deployment cost will all be very different. However, each country will need to consider what sustainable technologies are relevant to them, consider implementing them, and consider the reasons for doing so.”
According to Vivek, decarbonisation entails significant economic transformation. When new business opportunities arise in Asia, companies must contemplate how they will be the first to take advantage. To do this, they must seriously consider the technologies and industries they want to innovate in or implement and the various business models they should use to take these opportunities.
There will be an acceleration of the energy transitions if individuals in the nation change their behaviour, the government considers how the empowering regulations should be made, or how businesses decide how they will operate.
Vivek has led several large-scale transformations and new business builds across the region, such as for an energy conglomerate in Indonesia. From this experience, he is convinced that a fundamentally different way of thinking about any business problem is required.
It requires thinking about what the unique value proposition is going to be and thinking about getting new talent to build a business from the ground up. Some of his most memorable moments on this journey include realising the value of having the right talent.
Another thing he learned is that customer preferences change at very different levels. So, thinking about the organisation’s unique value propositions and how customers perceive them becomes very important. For incumbents, choosing different business models can also be essential.
Both private and public organisations are aware that change needs to occur quickly. Resources are becoming harder to come by while demand is rising, necessitating a balance to build a sustainable future. “Green technologies will help the world achieve sustainable levels and make the environment cleaner and safer for everyone.”
Urban Ideas and Solutions Through LKYGBPC
Vivek is on the International Judging Panel (IJP) of the Lee Kuan Yew Global Business Plan Competition (LKYGBPC), a biennial global university start-up challenge held in Singapore.
As a member of the judging panel charged with driving, developing, and upholding the entrepreneurial spirit of the LKYGBPC participants, Vivek is focused on the innovativeness of the solutions, such as how effectively the technology solves the problem.
He also believes that feasibility and how the different technologies are correctly implemented can significantly change the world. “These two parameters will be quite useful in considering how we are selecting, or how I would select various technologies.”
He acknowledges that innovative entrepreneurship talent can be cultivated wider in the broader community through such competitions. These serve as an illustration of how they are fostering innovation and entrepreneurship across society.
The competition is also one example of instilling a culture where the next generation is thinking about how things can be done differently. Competitors explore creative ideas and have a forum where they can share their thoughts, which can be a great example of nurturing innovation.
The competition, which is run by the Institute of Innovation and Entrepreneurship at Singapore Management University (SMU), is centred on urban ideas and solutions developed by student founders and early-stage start-ups. It is positioned as a campus innovation movement that seeks to establish a global startup ecosystem with financial backers, including venture capitalists, corporate oligopolies, and governmental organisations.
“I believe many of our leading schools are doing a great job of instilling a culture where children are thinking about how things can be done differently and what are creative ideas,” Vivek opines.
There are numerous instances throughout the world where the technologies or solutions used by youth or larger communities have truly made a meaningful difference. “But it does take some significant effort to raise awareness and establish a forum where people can discuss their concerns, share their ideas, and obtain the resources needed to solve them,” Vivek concludes.
Indonesia has great ambitions for its digital economy and has deployed strategies to achieve its ambitions with a goal to reach USD315 billion by 2030. The 2021-2024 Indonesia Digital Roadmap is set on 4 pillars, namely digital infrastructure, digital government, digital economy and digital society.
As part of its strategy, the government is promoting four important digital skills to accelerate its digital economy. The government believes that the future demand for digital skills will be focused on four areas Artificial Intelligence, Bitcoin, Cloud Computing, and Data Analytics (ABCD). The ABCD skills are projected to help the national economy hit its US$315 billion by 2030 target.
Therefore, the Indonesian government is encouraging young people to start businesses through a variety of free programs such as Beta School, 1,000 Startup Movement, Startup Studio, HUB.ID and IGDX.
“Aside from university disciplines, the ABCD is becoming increasingly important for everyone. I believe that all young people require ABCD,” stated Dedy Permadi, Expert Staff of the Minister of Communication and Informatics, in a discussion forum.
Mastering ABCD technical hard skills apart, Indonesian digital talents are also expected to be proficient in non-technical or soft skills known as the 4C’s, which are Complex Problem Solving, Critical Thinking, Creativity and Communication.
The Director of SDPPI Kominfo, Ismail, expressed his hope that the young generation in Indonesia would capture the golden opportunity for digitalisation. Digitalisation will transform Indonesia from a consumer country to a prominent player in the new normal.
The government recognises the importance of good infrastructure support in boosting the digital economy. As a result, the government is working to ensure an equitable distribution of internet connection networks across Indonesia, particularly in frontier, remote, and underdeveloped (3T) areas.
According to Ismail, the development of ICT infrastructure must meet three criteria: broad coverage, the deployment of a fibre-optic cable network on the backbone, and affordability, which means that the price is reasonable for the community.
Private operators focus on developing infrastructure in high-demand urban areas and, as a result, the digital divide between cities and towns has grown wider. Consequently, the government is beginning to develop 3T telecommunications in rural, underserved areas.
“We cannot rely solely on private-sector investment. To speed up and accelerate digital transformation, the government must invest in infrastructure,” Ismail said emphatically.
The Ministry of Communication and Information Agency and Telecommunications and Information Accessibility (BAKTI) have also worked to improve and expand internet access for public services throughout Indonesia. BAKTI is working with telecommunications companies to build Base Transceiver Stations (BTS) in remote areas of Indonesia.
“We hope to finish building BTS in all remote areas by 2023 and connect them to the 4G network,” Deddy stated.
Indonesia is a vast archipelagic country. So, relying solely on fibre optic cable networks will make it difficult to provide connectivity. As a result, the government is combining the fibre optic cable network constructed with the 150 Gbps SATRIA 1 satellite.
This multifunctional satellite can provide internet access to 150,000 public service locations in Indonesia, including educational institutions, local governments, defence and security administration, and health facilities. This satellite is scheduled to launch in 2023.
The government has begun construction of the first National Data Centre in the Delta Mas Region, GIIC, Cikarang District, Bekasi Regency, West Java Province, in connection with its digital strategy. It will then gradually expand data centres in Nongsa Digital Park in Batam, Riau Archipelago, the new National Capital City (IKN) in Balikpapan, East Kalimantan, and Labuan Bajo, East Nusa Tenggara.
The creation of this government data centre is intended to promote efficiency, effectiveness, state data sovereignty, and national data consolidation as part of the One Data Indonesia initiative. “This (data centre) is critical because government data management is critical to developing society’s transformation into a digital society,” Deddy said.
The Indonesian government disclosed four potential uses of Big Data and AI to improve its e-government programmes. These two technologies, they feel, have the potential to support disaster identification and preventive action, prevention of illegal activities and cyber-attacks and increase workforce effectiveness.
The Director General of Informatics Applications, Semuel A. Pangerapan, explained several scenarios for Big Data. According to him, the government can use Big Data to improve critical event management and the quality of the response by identifying problem points through Big Data Analytics. For example, the agencies can be better prepared to prevent and mitigate natural disasters such as drought, epidemics or massive accidents occur.
In addition, Big Data can also enhance the government’s ability to prevent money laundering and fraud through better surveillance to detect such illegal activities.
Furthermore, Big Data significantly reduces the possibility of cyber-attacks. Cyber-attacks can come from external parties, data leaks or internally for a variety of reasons. An analysis of patterns and unusual activities can help in preventing or managing such cyber issues.
Big Data and analytics can contribute to workforce effectiveness by increasing monitoring. In addition, it can be used for policy design, decision-making and gaining insights.
Semuel stressed the importance of data analysis after collecting all data in the right fashion. Data is only valuable if it is collected correctly and then analysed – data will only provide benefits if processed in the right way. “In its implementation, AI helps analyse existing Big Data, providing data understanding or insight to help make decisions,” he explained.
Another advantage of AI is the ability to speed up new implementation services and corrections in real-time. At the evaluation stage, AI can also provide suggestions for adjustments and improvements to subsequent policies.
Currently, the encourages the improvement of the quality of Big Data and AI innovation through the development of e-government. The Indonesian government is also open to third parties to accelerate Big Data and AI use.
E-government has made progress in recent years and received appreciation from the United Nations in 2020. The UN said that Indonesia’s e-government development index rose to rank 88 from previously ranked 107 in 2018. Indonesia’s e-participation index has also increased from rank 92 in 2018 to 57 in 2022.
“The two rankings show an increase in the quality of Indonesia’s e-government and the level of community activity in using e-government services,” said Semuel.
However, the government faced challenges in implementing these two technologies. Overlapping and data replication is one of the main problems. “Regulatory obstacles in the procurement of government Big Data infrastructure also need to be overcome. Then compliance with international standards for the national Big Data ecosystem is also still the government’s homework.”
To optimise AI use, Semuel emphasised the need for a skilled workforce, regulations governing the ethics of using AI, infrastructure, and industrial and public sector adoption of AI innovations.
The government is implementing several solutions to overcome challenges. First, they have provided suitable facilities in the form of National Data Centres (NDCs) in four separate locations. The NDCs will accommodate Government Cloud and contain national data across sectors.
Optimisation of data centre utilisation needs to be supported by staff with qualified expertise. For this reason, the government is holding digital skills training on AI and Big Data through the Digital Talent Scholarship (DTS) and Digital Leadership Academy (DLA) programs.
Apart from facilities and upskilling, Indonesia is looking to develop a business ecosystem that utilises AI and Big Data. Support for this comes from the National Movement of 1000 Digital Startups, Startup Studio Indonesia (SSI) and HUB.ID.
The Cyberspace Administration of China (CAC) announced a new certification for personal information protection and implementation. The office has decided to implement such certification to enhance its information protection capabilities and to promote the rational processing of personal information.
The certification implementation follows the Personal Information Protection Certification Implementation Rules. The implementation rules clarify that personal information processors must comply with the requirements of GB/T 35273 Information Security Technology Personal Information Security Specifications. The rules outline requirements for on-site audits, the evaluation and approval of certification results, post-certification supervision and certification time limits.
Organisations engaged in personal information protection certification work need approvals to carry out activities. The regulation applies to every personal information processor that carries out private information collection, storage, use, processing, transmission, provision, disclosure, deletion and cross-border processing activities.
The State Administration for Market Regulation and the State Internet Information Office decided to implement personal Information protection certification. The step is relevant to provisions of the Personal Information Protection Law of the People’s Republic of China (‘PIPL’). The body requires the Specifications for Security Certification of Cross-Border Processing of Personal Information for cross-border personal information processing.
The latest versions of the standards include technical verification, on-site audit, and post-certification supervision. In addition, the certification body shall clarify the requirements for certification entrustment materials, including but not limited to the basic materials of the certification client, the certification power of attorney, and relevant certification documents.
To get certified, an organisation must submit certification entrustment materials according to the certification body’s requirements and the certification body shall give timely feedback on whether it is accepted after reviewing the materials.
The materials are then used for determining the certification plan, including the type and quantity of personal information, the scope of personal information processing activities, information on technical verification institutions, etc., before notifying the organisation seeking certification.
The CAC stated certification is valid for three years. An organisation must submit a certification commission within six months before the expiration of the validity period. The certification body shall adopt the method of post-certification supervision and reissue new certificates to those that meet the certification requirements.
Violations, cheating, and other behaviours that seriously affect the implementation of the certification on the certification client or personal information processor will cancel the certificate. Therefore, certification bodies shall adopt appropriate methods to implement post-certification supervision to ensure that certified personal information processors continue to meet certification requirements. The certification body comprehensively evaluates the post-certification surveillance conclusions and other relevant information. If the evaluation is passed, the certification certificate can continue to be maintained.
The organisation shall actively cooperate with the certification activities. During the validity period of the certification certificate. If the name and registered address of the certified personal information processor, or the certification requirements, certification scope, etc., change, the certification principal shall submit a change entrustment to the certification body.
When changes happen, the certification body must evaluate the change in entrustment materials. The result will determine whether the body can approve the change. If technical verification or on-site audit is required, the body shall conduct technical and on-site audits before the change is approved.
When a certified personal information processor no longer meets the certification requirements, the certification body will promptly suspend or revoke the certification certificate. The certification principal can apply for the suspension and cancellation of the certification certificate within the validity period of the certification certificate.
Caltech engineers collaborated with the University of Southampton in England to design an ultrahigh-speed data transfer chip. The chip integrates both an electronics chip and a photonics chip which uses light to transfer data. It took four years to complete, from the initial idea to the final test in the lab.
“As the world becomes increasingly connected, and every device generates more data, it is exciting to show that we can achieve such high data rates while burning a fraction of power compared to the traditional techniques. We had to optimise the entire system all at the same time, which enabled achieving a superior power efficiency,” said Azita Emami, the Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering, Executive Officer for Electrical Engineering and senior author of the paper.
The research paper is titled “A 100Gb/s PAM4 Optical Transmitter in A 3D-Integrated SiPh-CMOS Platform Using Segmented MOSCAP Modulators.” Rockley Photonics and the U.K. Engineering and Physical Sciences Research Council funded this research.
The need for high processing power and transmission creates the inevitable excess heat. Heat is the enemy of the speed and the amount of data a computer device can manage. It happens not just for personal computers or laptops but also for data centres.
While a laptop may heat up while when in use, servers in data centres also heat up as they work – but at a much grander scale. Therefore, managing heat in the data centre is essential. The less heat, the more computing power is generated and the greater the volume of information it can handle.
Hence, engineers tried to find a way to increase the processing speed while keeping the heat low. The solution was to design and co-optimise an electronics chip and a photonics chip. The chip is innovative because it integrates an electronic circuit essential for data processing, combined with a photonics chip which is the most efficient piece for data transmission.
The Caltech/Southampton integrated chip can transmit 100 gigabits of data per second! Moreover, the integrated chip generates minimal heat, producing just 2.4 pico-Joules per transmitted bit. The result increases the electro-optical power efficiency by 3.6 times compared to the current technology.
Handling Next-level Computing
In the future, data centres will manage very high volumes of data compared to today. The new design integrated chip will answer a continuous demand for increasing data communication speed in data centres and high-performance computers.
“As the computing power of the chips scale, the communication speed can become the bottleneck, especially under stringent energy constraints,” Emami explained.
The high-demand data transmission and processing from a data-demanding task, such as a video call, streaming a movie, or playing an online video game, need high processing power in the data centre.
“There are more than 2,700 data centres in the U.S. and more than 8,000 worldwide, with towers of servers stacked on top of each other to manage the load of thousands of terabytes of data going in and out every second,” says a Caltech graduate student Arian Hashemi Talkhooncheh (MS ’16), lead author of a paper describing the two-chip innovation that was published in the IEEE Journal of Solid-State Circuits.
