Abstract

In this article, the RIPEMD-160 hash function is studied in detail. To analyze the hash function, we have extended existing approaches and used recent results in cryptanalysis. While RIPEMD and RIPEMD-128 reduced to 3 rounds are vulnerable to the attack, it is not feasible for RIPEMD-160. Furthermore, we present an analytical attack on a round-reduced variant of the RIPEMD-160 hash function. To the best of our knowledge this is the first article that investigates the impact of recent advances in cryptanalysis of hash functions on RIPEMD-160.
