A Security Grid Portal Using PKI and Online Proxy Certificate Repository

With the development of grid service, there are two key problems to be improved. One is to access Web grid service with friend interface for user. Another is the security authentication for grid resource share. Nowadays, a solution of Web universal entrance for grid service has been given through a Web framework named grid portal. PKI based grid security infrastructure has been widely used in order to guarantee grid security. However, although proxy certificate has been well applied in GSI, there is still no integrated model for security grid portal based on PKI and proxy mechanism. From the view of cooperation, a security grid portal is proposed based on PKI and online proxy certificate repository. It can successfully move the user's credential from the PKI public key certificates to its proxy certificate issued by online proxy certificate repository, which makes a Web user be easily authenticated through Web client to any grid service process
