The Research And Development Of Information Security Based On PKI

With the swift development of Internet and Electronic Commerce, Information Security became standing out more and more.How to insure authentication,integrity, confidentiality, and non-repudiation of information on web has became a predominant task in domain of information security and Electronic Commerce. PKI(Public Key Infrastructure) technique adopting digital certificate,Certification Authority, security protocol of network communication based on cryptograph of nowdays, it can provide multifarious service of safty for varying user in terms of varying needs of safty.So it is a better solution to the task.With closed research every technology of PKI, We discuss the basic knowledge , structure, Certification Authority of PKI and the design of transactionin system, security protocol of transactionin in particular.We design and develop a site of secure transactionin system based on PKI in terms of needs of actual application. This paper consist of two parts:· The Research of PKI : discusses the key technology of Information Security based on PKI.· The Development of PKI system: discusses how to design and develop actual secure transactionin system on web using the key technology of PKI.
