Cryptanalysis of safer++

WebIn this paper we describe an integral distinguisher over 2 rounds of Safer++. It allows a practical attack against 3 rounds of Safer++128, as well as attacks on 4 rounds of … WebSAFER+ (Massey et al., 1998) was submitted as a candidate for the Advanced Encryption Standard and has a block size of 128 bits. The cipher was not selected as a finalist. Bluetooth uses custom algorithms based on SAFER+ for key derivation (called E21 and E22) and authentication as message authentication codes (called E1).

WebIn cryptography, integral cryptanalysis is a cryptanalytic attack that is particularly applicable to block ciphers based on substitution–permutation networks. It was originally designed by Lars Knudsen as a dedicated attack against Square, so it … WebOur contribution is the analysis of two ciphers, Khazad and Safer++. We exploit the simple mathematical structure of a version of Khazad reduced from 8 to 5 rounds and show the existence of 264 weak keys that can be broken with 232 chosen plaintexts, 233 adaptively chosen ciphertexts and 240 steps of computation. The weak keys are a… nada.kth.se
