Analyzing Side-Channel Attack Vulnerabilities at RTL

Abstract

How much the timing side-channel attacks' vulner-ability can be mitigated at the early RTL design phase? This paper summarizes an Invited Talk presenting basic approaches for analyzing timing side-channel attack vulnerability in a generic information flow (illustrated on an RSA algorithm implementation) and in a common security architecture. The latter assumes, as an example, a Physical Unclonable Function (PUF) based chip-level authentication structure with potentially vulnerable ECC-powered Fuzzy Extractors.
