摘　　要：杂凑运算又称为消息摘要运算,可把任意长度的消息迭代,压缩成固定长度的字符串,该字符串又称为信息指纹,在信息安全领域具有重要作用。本文主要对比了我国研究制定的杂凑算法标准SM3杂凑算法和MD5、SHA-1、SHA-256等国际杂凑算法的计算流程,从迭代、压缩及安全性方面分析了SM3算法的优点。同时对SM3算法的实现提出了优化方案,并与其它杂凑算法进行了性能对比。本文对于杂凑算法的选择具有参考意义。The hash operation,also known as message digest operation,can convert messages of any length into a fixed-length string called information fingerprint by iterating and compressing. And it plays an important role in the field of information security. This paper mainly compares the standard SM3 hash algorithm and the international hash algorithms of MD5,SHA-1,SHA-256 on calculation process,and analyzes the advantages of SM3 over others from aspects of iteration,compression and security. At the same time,the optimization scheme is proposed for the implementation of SM3 algorithm,and performance comparison with other hash algorithms is carried out. This paper has reference significance for the selection of hash algorithms.
