Cryptanalysis of safer++
WebIt allows a practical attack against 3 rounds of Safer++128, as well as attacks on 4 rounds of Safer++128 and Safer++256 (without the last key addition layer), 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[9]. 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 …
