Cryptanalysis of the hash functions md4 and ripemd

open access: yes, 2005
. MD4 is a hash function developed by Rivest in 1990. It serves as the basis for most of the dedicated hash functions such as MD5, SHAx, RIPEMD, and HAVAL. In 1996, Dobbertin showed how to find collisions of MD4 with complexity equivalent to 220 MD4 hash

Practical collision attack on 40-step RIPEMD-128 [PDF]

open access: yes, 2013
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 $line2$ operation, and each operation has 64 steps ...

New (Two-Track-)MAC based on the two trails of RIPEMD: efficient, especially on short messages and for frequent Key-Changes

open access: yes, 2001
We present a new message authentication code. It is based on a two trail construction, which underlies the unkeyed hash function RIPEMD-160. It is in comparison with the MDx-MAC based on RIPEMD-160, much more efficient on short messages (that is on ...

Power Efficiency in Unfolding RIPEMD-160: Dynamic Power Analysis Using Gray Encoding in FPGA Design

open access: yesJournal of Physics: Conference Series
Abstract The RIPEMD-160 hash functions are extensively used in many cryptographic applications, including digital signatures, Hash Message Authentication Codes (HMAC) and others. Unfolding RIPEMD-160 was designed to analyse the architecture of the design in terms of ALUTs area and design speed.

Design of Optimized Pipelined RIPEMD-160 with High Frequency and Throughput [PDF]

open access: yes, 2016
The main objective of this paper is to design optimized pipelined RIPEMD-160 with efficient design strategies. There are two proposed designs in this paper such as iterative design and pipelined design.

Cryptanalysis of 48-step RIPEMD-160

open access: yesCryptanalysis of 48-step RIPEMD-160
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. Inspired by the way of computing the differential probability, we can do message modification such that a step differential hold with probability ...

Analysis and Design of SHA-V and RIPEMD-V with Variable Output-Length

open access: yes, 2003
A hash function provides services of information security, authentication, integrity and non-reputation in a branch of information security. Cryptographic hash functions had been developed since MD4 was proposed by Rivest. U.
