| Abstract(in English) | Tiger is a cryptographic hash function with 192-bit hash length which was proposed by Anderson and Biham in 1996. Although its structure is similar to widely used hash functions such as SHA-1 and MD5, the designers claim that Tiger has a stronger and faster avalanche coming from S-boxes from 8 bits to 64 bits. In FSE2006, Kelsey and Lucks presented collision attacks on Tiger reduced to 16 rounds out of 24 rounds with complexity 2^<44>, which has been the best attack so far. In this paper, we present an improved collision attack on Tiger reduced to 19 rounds with complexity 2^<69>. |
