Improved Cryptanalysis of Reduced RIPEMD-160
In this article, we propose an improved cryptanalysis of the double-branch hash function standard RIPEMD-160. Using a carefully designed non-linear path search tool, we study the potential differential paths that can be constructed from a difference in a single message word and show that some of these message words can lead to very good differential path candidates. Leveraging the recent freedo...
متن کاملRIPEMD-160: A Strengthened Version of RIPEMD
Cryptographic hash functions are an important tool in cryptography for applications such as digital fingerprinting of messages, message authentication, and key derivation. During the last five years, several fast software hash functions have been proposed; most of them are based on the design principles of Ron Rivest’s MD4. One such proposal was RIPEMD, which was developed in the framework of t...
متن کاملDifferential Attacks on Reduced RIPEMD-160
In this work, we provide the first security analysis of reduced RIPEMD-160 regarding its collision resistance with practical complexity. The ISO/IEC standard RIPEMD-160 was proposed 15 years ago and may be used as a drop-in replacement for SHA-1 due to their same hash output length. Only few results have been published for RIPEMD-160 so far and most attacks have a complexity very close to the g...
متن کاملOn the Collision Resistance of RIPEMD-160
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...
متن کامل2-Dimension Sums: Distinguishers Beyond Three Rounds of RIPEMD-128 and RIPEMD-160
This paper presents differential-based distinguishers against ISO standard hash functions RIPEMD-128 and RIPEMD-160. The compression functions of RIPEMD-128/-160 adopt the doublebranch structure, which updates a chaining variable by computing two functions and merging their outputs. Due to the double size of the internal state and difficulties of controlling two functions simultaneously, only f...
