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

Journal 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.

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

, 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 ...

Cryptanalysis of 48-step RIPEMD-160

Cryptanalysis 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

, 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.

ColliderScript: Covenants in Bitcoin via 160-bit hash collisions [PDF]

We introduce a method for enforcing covenants on Bitcoin outputs without requiring any changes to Bitcoin by designing a hash collision based equivalence check which bridges Bitcoin\u27s limited Big Script to Bitcoin\u27s Small Script.
