HAVAL is a cryptographic hash function proposed in 1992 by Zheng, Pieprzyk and Seberry. Its structure is quite similar to other widely used hash functions such as MD5 and SHA-1. The specification of HAVAL includes a security parameter: the number of passes (that is, the number of times that a particular word of the message is used in the computation) which can be chosen equal to 3, 4 or 5. In this paper we cryptanalyze the compression functions of the 4-pass and the 5-pass HAVAL using differential cryptanalysis. We show that each of these two functions can be distinguished from a truly random function.
