The Research And Application Of Security For Web Service Based On PKI Technology

With the development and popularity of the internet,the network has become a part of the people's life. Everday,there are many businesses and individuals being busy on the network.The people can share the information and documents by using the E-mail and the network.All the businesses are tring to use the E-commerce instead of the traditional transaction.All the above has promoted the development of the information technology.We benefited from the characters of open and anomymity of the network,however,these characters also make the network become insecurity.To solve the security problem,we must set up a believable institution on the network and this has become the most important problem.After the research of many countries,there has formed a set of scheme-PKI to solve the security problem.PKI is a system providing security service based on publicse key theories.PKI give us a approach of development and tactics ,so we can be sure authentication and Non-Repudiation.PKI technology will become the base of E-commerce and E-government affairs and PKI technology will become the main technology for network security. In this paper,we research the PKI structure , research the Web security based on the PKI structure,and try to apply PKI security structure to the web security services,so we can solve the problem of important datas being revealed and the problem of E-commerce and E-government affairs' belief and set up the believable digital commercal environment and government affairs environment.Finally,we give an example of ebank security web service based on the PKI technology.
