Type Classification against Fault Enabled Mutant in Java Based Smart Card

Smart card are often the target of software or hardware attacks. For instance the most recent attacks are based on fault injection which can modify the behavior of applications loaded in the card, changing them as mutant application. In this paper, we propose a new protection mechanism which makes application to be less prone to mutant generation. This countermeasure requires a transformation of the original program byte codes which remains semantically equivalent. It requires a modification of the Java Virtual Machine which remains backward compatible and a dedicated framework to deploy the applications. Hence, our proposition improves the ability of the platform to resist to Fault Enabled Mutant.
