Pki Technology In Army Document Flow System Realization

E-military Affairs System means that applying conventional martial management to network, especially means undercover martial action on internet. Its security is very important. A important condition of E-military Affairs System base on internet is network security, and security is basal guarantee of E-military Affairs System.PKI (Public Key Infrastruture) is a security infrastruture which provide security service by cipher arithmetic. Applying PKI to E-military Affairs System can enhancesecurity of E-military Affairs System. And E-military Affairs System base on PKI technology have a very good foreground.First of all,this paper analyse the theory of PKI technology, introduce the function and systemstructure of PKI, and introduce the basal theory that symmetricalcipherarithmetic and unsymmetricalcipherarithmetic and X.509 standard. At the same time, this paper simply introduce SSL (Secure Socket Layer) which is applied on networksecurecommunications.Afterward, Advance the security requirement of E-military Affairs System via analysing the actuality and familiar risk.Next, this paper advanced project of network security of E-military Affairs System, include structure and buildup of system. Particularly, design the PKI/CA system which is the core of system security.In the end, advance the project of security requirement of E-military Affairs System base on PKI/CA system, and program the theory in E-military Affairs System.
