Collision attacks on AES-192/256,Crypton-192/256,mCrypton-96/128,and anubis

At aes'00,a collision attack on 7-round reduced aes was proposed. in this paper,we apply this idea to seven spn block ciphers,aes-192/256,crypton-192/256,mcrypton-96/128,and anubis. applying our attacks on aes-192/256,we improve the attack result based on meet-in-the-middle attack (aes-192) and the attack result proposed in aes'00 (aes-256),respectively. our attack result on anubis is superior to known cryptanalytic result on it. in the cases of crypton-192/256 and mcrypton-96/128,our attacks are applicable to 8-round reduced versions. the attack results on mcrypton-96/128 are more practical than known cryptanalytic results on them. © 2013 jinkeon kang et al.
