Hardware security and reliability verification based on fault propagation model

Abstract

Large scale integrate circuits is facing serious threat such as design vulnerabilities, side channels, and hardware Trojans. Traditional functional verification method is difficult to ensure high test coverage, and it is also difficult to detect security vulnerabilities such as side channels and stealthy hardware Trojans. Formal verification methods focus on the equivalence and functional correctness of design, and are difficult to meet security and reliability verification needs. The present work proposes a hardware security and reliability verification method from formal model. The present method can develop formal models for describing the security and reliability behaviour of hardware designs. It can detect potential security vulnerabilities in hardware designs. Experimental results show that the verification method is effective in detecting sensitive information leakage and modification caused by side channels and hardware Trojans.
