Proposta de implementação dos algoritmos de hash MD5 e SHA-1 em hardware reconfigurável
… one to the MD5 algorithm and other to the SHA-1 algorithm implemented on Field Programmable Gate Array (FPGA) Xilinx Virtex 6 xc6vlx240t-1ff1156. The throughput and the occupied area were analyzed for several implementations on parallel instances of those algorithms. The results showed that …

Design and analysis of hash functions
… developed based on this construction. MD5, SHA-0 and SHA-1 are currently the most widely deployed hash functions. However, they were all broken by Wang using a differential collision attack in 2004 [55-60], which increased the urgency of replacement for these widely used hash functions. …

Hardware Evaluation of SHA-3 Candidates
… and exploits on the cryptographic hash function, SHA-1, the most widely used hash function of the secure hashing algorithm family. Although these attacks do not work on SHA-2, the next in the series of the secure hashing algorithm family, the National Institute of Standards and Technology still …

Vector Instruction Set Extensions for Efficient and Reliable Computation of Keccak
… Standard (AES), for the Secure Hashing Standard (SHA-1, SHA2) and for carry-less multiplication. These crypto-instructions are optimized for a single algorithm and provide significant performance improvements over software written using general-purpose instruction set. However, today's secure …

Security proofs for the MD6 hash function mode of operation
… commonly-used hash functions, such as MD4, MD5, SHA-0, and SHA1 [13, 38]. These culminated with the celebrated work of Wang, Yin, and Yu from 2005, which demonstrated relatively efficient methods for finding collisions in the SHA-1 hash function [37]. Although there are several cryptographic hash …

Algebraic and Logic Solving Methods for Cryptanalysis
… to a SAT solver that inverts the hash functions SHA-1 and SHA-2, we describe how to tweak the SAT solver using a programmatic interface such that the propagation of the solver and thus the attack itself is improved.
