Abstract

The cryptographic blocks used in the integrated circuits implement algorithms proved robust against cryptanalysis. However, malicious manipulation against the circuit itself can retrieve the secret data. Among known hardware attacks, attacks called "fault attacks" are proved particularly effective. Their principle is to inject a fault in the circuit (using for example a laser beam) that will produce an erroneous result and to compare it with a correct result. Therefore, it is essential to detect these errors during the circuit running. The work presented in this thesis concerns the concurrent detection of errors in cryptographic circuits, using as support the implementation of the Advanced Encryption Standard "AES". Thus, we analyze several...
