Abstract
Encryption algorithms could suffer fault injection attacks in order to obtain the secret key. In this paper, a specific protection for any round-based encryption algorithm is presented, analyzed and tested. It is providing a high degree of robustness together with a small penalty in the algorithm throughput when dealing with specific intentional attacks. Experimental results on advanced encryption standard are presented and discussed.
