Abstract :
Fault detection in encryption algorithms is gaining in importance since fault attacks may compromise even recently developed cryptosystems. We analyze the different operations used by various symmetric ciphers and propose possible detection codes and frequency of checking. Several examples (i.e., AES, RC5, DES and IDEA) are presented to illustrate our analysis.
