Rapidly developing digital technologies, together with social and business trends, are providing huge opportunities for innovation in product and service markets, and also in government processes. Technology developments drive socioeconomic and behavioural changes and vice versa, and the rate of change in these makes tracking and responding to high-speed developments a significant challenge in public and private sectors alike. Agile governance and policy-making for emerging technologies is likely to become a key theme in strategic thinking for the public and private sectors. Particular trends that are challenging now, and will increasingly challenge society include developments in technologies on the outskirts of the internet. These include Artificial Intelligence, not just in the cloud but in Edge computing, and in Internet of Things devices and networks. Alongside and in conjunction with this ecosystem, is Distributed Ledger Technology. Together this ensemble of technologies will enable innovations that promote productivity, like peer-to-peer dynamic contracts and other decision processes, with or without human sight or intervention. However, the ensemble's autonomy, proliferation and use in critical applications, makes the potential for hacking and similar attacks very significant, with the likelihood of them growing to become an issue of strategic national importance. To address this challenge, and to preserve the immense economic and productivity benefits that will come from the successful deployment and application of digital technologies 'at the edge', a focused initiative is needed. Ideally, this will use the UK's current platform of experience in the safe and secure application of the Internet of Things. The contributors to this platform include PETRAS partners, and several other centres of excellence around the UK. It is therefore proposed to build an inclusive PETRAS 2 Research Centre with national strategic value, on the established and successful platform of the PETRAS Hub. This will inherit its governance and management models, which have demonstrated the ability to coordinate and convene collaboration across 11 universities and 110 industrial and government User Partners, but will importantly step up its mission and inclusivity through open research calls for new and existing academic partners. PETRAS 2 will maintain an agile and shared research agenda that views social and physical science challenges with equal measure, and covers a broad range of Technology Readiness Levels, particularly those close to market. It will operate as a virtual centre, providing a magnet for collaboration for user partners and a single expert voice for government. User partner engagement is likely to be strong following the successes of the current PETRAS programme, which has raised over £1m in cash contributions from partners during 2018. The new PETRAS 2 'Secure Digital Technologies at the Edge' methodology will inherit the best of PETRAS, including open calls to the UK research community and a partnership-building fund that allows a responsive approach to opportunities that emerge from existing and new user and academic partnerships. PETRAS 2 will be driven by sectoral cybersecurity priorities while retaining a discovery research agenda to horizon-scan and develop understanding of new threats and opportunities. The scope of projects and the associated Innovate UK SDTaP demonstrators, spans early to late TRLs and aims to put knowledge into real user partner practice. Furthermore, the development of many early career researchers through PETRAS 2 research activities should lead to a step change in our national capability and capacity to address this highly dynamic area of socio-technical opportunity and risk.

Today we use many objects not normally associated with computers or the internet. These include gas meters and lights in our homes, healthcare devices, water distribution systems and cars. Increasingly, such objects are digitally connected and some are transitioning from cellular network connections (M2M) to using the internet: e.g. smart meters and cars - ultimately self-driving cars may revolutionise transport. This trend is driven by numerous forces. The connection of objects and use of their data can cut costs (e.g. allowing remote control of processes) creates new business opportunities (e.g. tailored consumer offerings), and can lead to new services (e.g. keeping older people safe in their homes). This vision of interconnected physical objects is commonly referred to as the Internet of Things. The examples above not only illustrate the vast potential of such technology for economic and societal benefit, they also hint that such a vision comes with serious challenges and threats. For example, information from a smart meter can be used to infer when people are at home, and an autonomous car must make quick decisions of moral dimensions when faced with a child running across on a busy road. This means the Internet of Things needs to evolve in a trustworthy manner that individuals can understand and be comfortable with. It also suggests that the Internet of Things needs to be resilient against active attacks from organised crime, terror organisations or state-sponsored aggressors. Therefore, this project creates a Hub for research, development, and translation for the Internet of Things, focussing on privacy, ethics, trust, reliability, acceptability, and security/safety: PETRAS, (also suggesting rock-solid foundations) for the Internet of Things. The Hub will be designed and run as a 'social and technological platform'. It will bring together UK academic institutions that are recognised international research leaders in this area, with users and partners from various industrial sectors, government agencies, and NGOs such as charities, to get a thorough understanding of these issues in terms of the potentially conflicting interests of private individuals, companies, and political institutions; and to become a world-leading centre for research, development, and innovation in this problem space. Central to the Hub approach is the flexibility during the research programme to create projects that explore issues through impactful co-design with technical and social science experts and stakeholders, and to engage more widely with centres of excellence in the UK and overseas. Research themes will cut across all projects: Privacy and Trust; Safety and Security; Adoption and Acceptability; Standards, Governance, and Policy; and Harnessing Economic Value. Properly understanding the interaction of these themes is vital, and a great social, moral, and economic responsibility of the Hub in influencing tomorrow's Internet of Things. For example, a secure system that does not adequately respect privacy, or where there is the mere hint of such inadequacy, is unlikely to prove acceptable. Demonstrators, like wearable sensors in health care, will be used to explore and evaluate these research themes and their tension. New solutions are expected to come out of the majority of projects and demonstrators, many solutions will be generalisable to problems in other sectors, and all projects will produce valuable insights. A robust governance and management structure will ensure good management of the research portfolio, excellent user engagement and focussed coordination of impact from deliverables. The Hub will further draw on the expertise, networks, and on-going projects of its members to create a cross-disciplinary language for sharing problems and solutions across research domains, industrial sectors, and government departments. This common language will enhance the outreach, development, and training activities of the Hub.
