Design and implementation of twister algorithm based on FPGA

Abstract

Recent breakthroughs in cryptanalysis of standard hash functions like SHA-1 and MD5 raise the need for alternatives. The Twister hash function is developed by a team by Ewan Fleischmann in response to the call for proposals for a SHA-3 cryptographic hash algorithm by the National Institute of Standards and Technology. In this paper, introduces the logic structure of Twister algorithm. Using the structure advantage of FPGA hardware devices and give the FPGA Design and Implementation project of Twister algorithm. Final the timing simulation of some modules were given. © 2011 Springer-Verlag.
