Fault analysis of AEZ

Summary AEZ is a block cipher mode based on AES which uses three 128‐bit keys. The algorithm has been updated several times during the three rounds of the CAESAR cryptographic competition. Cryptanalytic results presented on AEZ to date do not breach its security. This paper describes a fault injection analysis on AEZ. We focus on analysing AEZ v4.2 but also investigate the applicability of these analyses to the recent version AEZ v5. This paper...
