A simple method for constructing collisions for Shpilrain’s polynomial-based hash function from ICISC 2006 is presented. The attack relies on elementary linear algebra and can be...

We present a collision attack on the hash function HAS-160 reduced to 53-steps. The attack has a complexity of about 235 hash computations. The attack is based on the work of Cho e...

At PKC 2000, Inoue and Sakurai proposed some methods to design hash functions from block ciphers and codes (block codes and convolutional codes). They claimed that their hash func...

The security of hash functions based on a block cipher with a block length of m bits and a key length of k bits, where k ≤ m, is considered. New attacks are presented on a large ...

We analyse the security of new hash functions whose compression function is explicitly defined as a sequence of multivariate equations. First we prove non-universality of certain ...
