On Analyzing Program Behavior under Fault Injection Attacks

Fault attacks pose a serious threat to cryptographic algorithm implementations. It is a non-trivial task to design a code that minimizes the risk of exploiting the incorrect output that was produced by inducing faults in the algorithm execution process. In this paper we propose a design of an instruction set simulator capable of analyzing the code behavior under fault attack conditions. Our simulator is easy to use and provides a valuable insights for the designers that could help to harden the code they implement.
