Memory-based Physical Unclonable Function (MemPUF) emerged as a replacement for traditional key preservation primitives to overcome the susceptibility of secret keys to physical attacks. Recent experiments demonstrated that even some MemPUFs can be physically attacked by exploiting their side-channel information. In this paper, we formulate an adversary model for a prediction attack that takes advantage...
Physical unclonable function (PUF) leverages the immensely complex and irreproducible nature of physical structures to achieve device authentication and secret information storage. To enhance the security and robustness of conventional PUFs, reconfigurable physical unclonable functions (RPUFs) with dynamically refreshable challenge-response pairs (CRPs) have emerged recently. In this paper, we propose...
Physical Unclonable Function (PUF) is widely known as an effective countermeasure to withstand non-invasive computational attacks as well as invasive tempering attacks on trusted computing systems. However, vast majority of the PUFs reported to-date are defined by static Challenge-Response Pairs (CRPs) with inferior security. In this paper, we propose a novel design of dynamically reconfigurable PUF...
