Collision Attacks on AES-192/256, Crypton-192/256, mCrypton-96/128, and Anubis

[摘要] At AES’00, a collision attack on 7-round reduced AES wasproposed. In this paper, we apply this idea to seven SPN block ciphers,AES-192/256, Crypton-192/256, mCrypton-96/128, and Anubis. Applyingour attacks on AES-192/256, we improve the attack result based onmeet-in-the-middle attack (AES-192) and the attack result proposed inAES’00 (AES-256), respectively. Our attack result on Anubis is superiorto known cryptanalytic result on it. In the cases of Crypton-192/256and mCrypton-96/128, our attacks are applicable to 8-round reduced versions. The attack results on mCrypton-96/128 are more practical thanknown cryptanalytic results on them.
