Security and trust are vital concerns in today’s digital age, namely in internet-based systems, automotive applications, and biomedical devices. With the drastically increasing number of interconnected devices in low-cost internet-of-things (IoT) applications, providing reliable, energy-efficient and cost-effective hardware (HW) security solutions becomes of paramount importance. Ubiquitous IoT devices face additional challenges because of varying environmental conditions and possible physical access by hackers. Moreover, it is necessary to ensure seamless system security hardware primitives for silicon produced elsewhere. Therefore, it is necessary to create and implement design flows to sustain the trust chain. It is critical for Europe to ensure that if silicon is produced in a non-trusted environment (more than 90% of silicon in advanced CMOS nanotechnologies, below 5nm, is produced in Asia), Europe still controls the trust chain, keeping the design capabilities and intellectual property. To further improve PUF (Physically Unclonable Functions) reliability, randomness, energy-efficiency, stability and robustness against ageing variations, several techniques will be used in SECURE for the design of new PUFs. The main innovation of the proposed hybrid PUF ID system is based on the hybrid combination of the best of two different technologies. On the one hand, to achieve a better static entropy source, we will use passive electronics printed directly on flexible substrates. This will ensure that our PUFs are primarily composed of better structures that amplify intra-die variations (due to the inherent process variability associated with low-temperature printing technologies). The use of cryptographic algorithms in hardware is also a novelty explored in the project. The two groups involved in this proposal, from Universidade NOVA de Lisboa (associated with CTS, CEMOP of UNINOVA and CENIMAT/I3N), and ISTAR-Iscte - Information Sciences, Technologies and Architecture Re...

The main objective of this project is to study intelligent textiles for pets, specifically in dogs, in order to validate a prototype with ‘Smart Textile’ technology that can be used by society to monitor the welfare of pet dogs, and if possible develop a prototype of this textile product.
