ERROR CORRECTION PROCEDURES FOR A HARDWARE IMPLEMENTATION OF THE ADVANCED ENCRYPTION STANDARD

The Advanced Encryption Standard algorithm itself does not guarantee error free operation or detection of arising errors. Contemporary research has shown that even single bit errors strongly affect the output of the algorithm. Moreover an attacker may maliciously induct errors during the run of the AES in order to perform cryptanalysis and recover the encryption secret key. In this paper we propose an extension of error detection code for AES, known from an open literature. The implementation of our idea leads to the improvement of error detection ability and reduces of the probability of successful fault analysis below 2-7.
