Abstract: SM4 Algorithm, short for SM4 Block Cipher Algorithm, was published in 2006 to promote the application of WAPI. It became a cryptography industrial standard (GMT 0002—2012) in March 2012 and a national standard (GBT 32907—2016) in August 2016. This paper describes SM4s calculating process, structural features and cryptographic properties. Furthermore, we introduce some latest researches on SM4s security and compare SM4s security with several international block cipher standards such as AES, HIGHT and MISTY1.

Key words: SM4 block cipher algorithm, differential cryptanalysis, linear cryptanalysis, S box

摘要: SM4分组密码算法简称为SM4算法,为配合WAPI无线局域网标准的推广应用,SM4算法于2006年公开发布,2012年3月发布成为国家密码行业标准(标准号为GMT 0002—2012),2016年8月发布成为国家标准(标准号为GBT 32907—2016).介绍了SM4分组密码算法的算法流程、结构特点及其密码特性,以及SM4算法的安全性分析研究现状,并与国际标准分组算法的安全性进行了对比.
