, 2006 Tiger is a cryptographic hash function with a 192-bit hash value which was proposed by Anderson and Biham in 1996. At FSE 2006, Kelsey and Lucks presented a collision attack on Tiger reduced to 16 (out of 24) rounds with complexity of about 244. Furthermore, they showed that a pseudo-near-collision can be found for a variant of Tiger with 20 rounds ...
