PKI系统支持SM2椭圆曲线公钥密码算法的研究

Study on Public Key Infrastructure in Support of Public Key Cryptographic Algorithm SM2 based on Elliptic Curves

目前各大部委、大型企业集团均建设有PKI系统,发放了大量数字证书,整合了大量应用,数字证书技术在中国得到了深入、全面的发展和应用。针对国家近期发布的关于公钥密码算法升级的要求,文中深入浅出地分析了国内PKI系统建设、应用的模式和现状,论述了相应的升级解决方案,指出了升级的关键环节,并指明了开展该项工作需要注意的问题。

Nowadays,China＇s major ministries and large enterprise groups all build Public Key Infrastructures（PKIs）,issue a large number of digital certificates and integrate a large quantity of applications. Digital certificate technology achieves in-depth and comprehensive development and application in China. For the state’s upgrade requirement of public key cryptography algorithm,this paper gives in-depth analysis of PKI construction,including its application model and present situation,tells of the appropriate upgrade solutions and key links,and finally points out the important problems needing attention in this work.
