title = "(Pseudo-) preimage attacks on step-reduced HAS-160 and RIPEMD-160",
abstract = "The hash function HAS-160 is standardized by the Korean government and widely used in Korea, and the hash function RIPEMD-160 is a worldwide ISO/IEC standard. In this paper, by careful analysis of the two hash functions, we propose a pseudo-preimage attack on 71-step HAS-160 (no padding) with complexity 2158.13 and a preimage attack on 34-step RIPEMD-160 (with padding) with complexity 2158.91. Both of the attacks are from the first step. The improved results are derived from the differential meet-in-the-middle attack and biclique technique etc. As far as we know, they are the best pseudo-preimage and preimage attacks on step-reduced HAS-160 and RIPEMD-160 respectively in terms of the step number.",
