| 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 underlying block cipher has a stronger and faster avalanche coming from S-boxes from 8 bits to 64 bits. In this paper, we analyze the compression function of Tiger by studying security of the underlying block cipher called Tiger in encryption mode against differential style attacks. We show attacks on Tiger in encryption mode reduced to 15 rounds (out of 24 rounds). |
