[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
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. ...
Furthermore, we present an analytical attack on a round-reduced variant of the RIPEMD-160 hash function. ...
Based on the similar design of RIPEMD-160, MD5, SHA-1, and its predecessor RIPEMD, one might doubt the security of RIPEMD-160. ...

Because of recent progress in the cryptanalysis of these hash functions, we propose a new version of RIPEMD with a 160-bit result, as well as a plug-in substitute for RIPEMD with a 128-bit result. ...
One such proposal was RIPEMD, which was developed in the framework of the EU project RIPE (Race Integrity Primitives Evaluation). ...

This paper describes the study of cryptographic hash functions, one of the most important classes of primitives used in recent techniques in cryptography. ...
The performance of the new hash function is at least 30% better than that of SHA-256 in software. And it is secure against any known cryptographic attacks on hash functions. ...
On the other hand, in case of RIPEMD-128/160, there is no attack result because RIPEMD-128/160 have different message-ordering in branches. ...
