摘要
Abstract
The Twister algorithm is one candidate algorithm of SHA-3,a typical block cipher algorithm based on AES stuc-ture.This paper describes the current attack technology on Twister, and analyses computational complexity as well.Using the rebound attack, a feasible differential path is designed to analyse the collision attack on the maxi-round of Twister and obtain the collisions whose complexity are 2128 and 2184 respectively.Based on the analysis of the collision attack on the compression function of Twister,the computational complexity can be reduced.关键词
