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.
