Automating Collision Attacks on RIPEMD-160 [PDF]
IACR Transactions on Symmetric Cryptology, 2023 As an ISO/IEC standard, the hash function RIPEMD-160 has been used to generate the Bitcoin address with SHA-256. However, due to the complex doublebranch structure of RIPEMD-160, the best collision attack only reaches 36 out of 80 steps of RIPEMD-160 ...

New Semi-Free-Start Collision Attack Framework for Reduced RIPEMD-160 [PDF]
IACR Transactions on Symmetric Cryptology, 2019 RIPEMD-160 is a hash function published in 1996, which shares similarities with other hash functions designed in this time-period like MD4, MD5 and SHA-1.

Cryptanalysis of 48-step RIPEMD-160
IACR Transactions on Symmetric Cryptology, 2017 In this paper, we show how to theoretically compute the step differential probability of RIPEMD-160 under the condition that only one internal variable contains difference and the difference is a power of 2.

A unified architecture of MD5 and RIPEMD-160 hash algorithms [PDF]
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004 Hash algorithms are important components in many cryptographic applications and security protocol suites. In this paper, a unified architecture for MD5 and RIPEMD-160 hash algorithms is developed.

Analysis of RIPEMD-160: New Collision Attacks and Finding Characteristics with MILP [PDF]
IACR Cryptology ePrint Archive, 2023 The hash function RIPEMD-160 is an ISO/IEC standard and is being used to generate the bitcoin address together with SHA-256. Despite the fact that many hash functions in the MD-SHA hash family have been broken, RIPEMD-160 remains secure and the best ...

On the Collision Resistance of RIPEMD-160 [PDF]
Information Security Conference, 2006 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,

Differential Attacks on Reduced RIPEMD-160 [PDF]
Designs, Codes and Cryptography, 2012 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 ...

Distinguishers on Double-Branch Compression Function and Applications to Round-Reduced RIPEMD-128 and RIPEMD-160 [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2013 SUMMARY This paper presents differential-based distinguishers against double-branch compression functions and applies them to ISO standard hash functions RIPEMD-128 and RIPEMD-160. A double-branch compression function computes two branch functions to update a chaining variable and then merges their outputs.

Collisions and Semi-Free-Start Collisions for Round-Reduced RIPEMD-160 [PDF]
International Conference on the Theory and Application of Cryptology and Information Security, 2017 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.
