WebJun 8, 2010 · In this paper we consider the security of block ciphers which contain alternate layers of invertible S-boxes and affine mappings (there are many popular cryptosystems which use this structure, including the winner of the AES competition, Rijndael). Web1 As a recent cryptanalysis of round reduced versions of block-cipher SAFER++ shows, breaking 3 rounds of well-designed SPN via conventional differential or linear attacks …
WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. 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. 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).
WebThe attacks in the paper are practical up to 4 rounds. The methods developed to attack SAFER++ can be applied to other substitution-permutation networks with incomplete diffusion.
