Project Summary: 

As the world becomes ever more connected, the vast number of Internet of things (IoT) devices expected in the next 5 years will necessitate the use of smart, autonomous machine-to-machine (M2M) communications; however this poses serious security and privacy issues as we will no longer have direct control over with whom and what our devices communicate. Counterfeit, hacked, or cloned devices acting on a network can cause significant damage, in terms of both monetary costs (for example hacking of smart meters to falsify readings) as well as danger to life due to connected cyber-physical systems (for example the recent Jeep hack where attackers could remotely kill the engine and control the steering). However, for many of the low-cost IoT devices, strong cryptography can be problematic due to the lightweight computational and memory capabilities of these devices. To address this problem the proposed PhD project will investigate multi-Physical Unclonable Function (PUF) designs, thereby enabling lightweight, and secure authentication mechanisms. A PUF is a digital circuit that can extract a unique digital fingerprint from an electronic device based on the underlying inherent variability in its manufacturing process.
