摘要 校正了CANS2010会议上Minier等人关于GrФstl区分器的分析结果,改进了GrФstl算法中压缩函数的积分区分器,充分利用渗透技术首次提出了关于P函数和Q函数的11轮积分区分器。虽然针对散列函数的分析是目前SHA3研究的主流,但是所提出的关于积分区分器的研究反映了压缩函数的随机性,对新的散列函数的设计具有重要意义。 Firstly, the distinguisher of Grcstl-512 proposed by Minier in CANS 2010 was corrected. Then, the integral distinguisher of Grostl-512 compression function was improved. By using the saturation technique new 11-round integral distinguishers of P function and Q function were proposed. Whereas the SHA-3 competition focuses the attacks of hash functions, the proposed analysis on integral distinguish reflect the randomness of the compression function, which is of great significance to design new hash function.
