SHA-3的安全性分析
Security analysis of SHA-3
摘要
Abstract
In order to evaluate the new hash standard SHA-3,this paper conducted a security analysis of it from the perspec-tive of statistical performance and symmetrical property of round permutation Keccak-f.The results show that SHA-3 possesses favorable avalanche effect,and average number of changed bits and average probability of changed bits are both very close to the ideal value with a small standard deviation.It has high stability and low collision degree.The ιmapping which was used to add round constants could seriously disrupt the symmetry of Keccak-f.Thus,internal differential attack could only be achieved in a limited numbers of rounds.关键词
