New Semi-Free-Start Collision Attack Framework for Reduced RIPEMD-160
hash function RIPEMD-160 freedom degree utilization
2019/6/10
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. However, for RIPEMD-160, no (semi-free-start)...
In this paper, we re-consider the connecting techniques to find colliding messages, which is achieved by connecting the middle part with the initial part. To obtain the best position of middle part, w...
In this paper, we propose a new cryptanalysis method to mount collision attack on RIPEMD-160. Firstly, we review two existent cryptanalysis methods to mount (semi-free-start) collision attack on MD-SH...
Collisions and Semi-Free-Start Collisions for Round-Reduced RIPEMD-160
RIPEMD-160 semi-free-start collision collision
2017/8/29
In this paper, we propose an improved cryptanalysis of the double-branch hash function RIPEMD-160 standardized by ISO/IEC. Firstly, we show how to theoretically calculate the step differential probabi...
In this article we propose a new cryptanalysis method for double-branch hash functions that we apply on the standard RIPEMD-128, greatly improving over know results. Namely, we were able to build a ve...
Improved Cryptanalysis of Reduced RIPEMD-160
semi-free-start collision compression function
2014/3/7
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 differentia...
RIPEMD-128 is an ISO/IEC standard cryptographic hash function proposed in 1996 by Dobbertin, Bosselaers and Preneel. There are two different and independent parallel lines called $line1$ operation and...
Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD
Hash Functions MD4 MD5 HAVAL-128 RIPEMD
2009/3/27
MD5 is the hash function designed by Ron Rivest [9] as a strengthened version of MD4 [8]. In 1993 Bert den Boer and Antoon Bosselaers [1] found pseudo-collision for MD5 which is made of the same messa...
