Crytanalysis of SAFER++
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. The methods developed to attack SAFER++ can be applied to other substitution-permutation networks with incomplete diffusion.
