WebSAFER++, a variant of SAFER+, was among the cryptographic primitives selected for the second phase of the NESSIE project. The block size is 128 bits and the key size can take either 128 or 256 bits. The number of rounds for SAFER++ is 7 for keys of 128 bits, and 10 for keys of 256 bits. Both ciphers use PHT as their linear transformation. WebCryptanalysis of Safer++ . Alex Biryukov, Christophe De Cannière, Gustaf Dellkrantz; Pages 195-211. Public Key Cryptanalysis II.

This paper presents several multiset and boomerang attacks on Safer++ up to 5.5 out of its 7 rounds. These are the best known attacks for this cipher and significantly improve the previously known results. The attacks in the paper are practical up to 4 rounds. 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 buffaloe bowling lanes
