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). WebThis 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.

WebZero-correlation Linear Cryptanalysis of SAFER Block Cipher Family Using the Undisturbed Bits The Computer Journal Oxford Academic Abstract. SAFER is a family of block ciphers, which is comprised of SAFER K, SAFER SK, SAFER+ and SAFER++. SAFER SK was proposed to strengthen the key schedule WebIt allows a practical attack against 3 rounds of Safer++128 , as well as attacks on 4 rounds of Safer++128 and Safer++256 , under the chosen-plaintext hypothesis. These results achieve much lower complexity than the currently known best attacks on Safer++, namely weak-key linear cryptanalysis by Nakahara[8].
