High reliability is a desirable property of any implementation of the Advanced Encryption Standard (AES). To achieve high reliability, all possible faults must be detected to avoid the use and transmission of erroneous encrypted/decrypted data. In this paper we first study the behavior of faults which may occur during the encryption and decryption procedures of AES, and the way such faults eventually propagate to the final result. We then describe an appropriate detection technique for these faults. This work extends our preliminary results (G.

Abstract

High reliability is a desirable property of any implementation of the Advanced Encryption Standard (AES). To achieve high reliability, all possible faults must be detected to avoid the use and transmission of erroneous encrypted/decrypted data. In this paper we first study the behavior of faults which may occur during the encryption and decryption procedures of AES, and the way such faults eventually propagate to the final result. We then describe an appropriate detection technique for these faults. This work extends our preliminary results (G. Bertoni et al, MPCS 2002) by considering more general fault models (e.g., permanent and multiple transient faults), and the possibility of fault masking.
