We show in this paper how several proposed Physical Unclonable Functions (PUFs) can be broken by numerical modeling attacks. Given a set of challenge-response pairs (CRPs) of a PU...

Abstract. Several types of logic gates suitable for leakage-proof computations have been put forward [1,2,3,4]. This paper describes a method, called “backend duplication” to a...
