A Study on the Efficient Mutual Authentication Mechanism Using the Agent Server

The communication technology developed into the electronic commerce using the radio communication through the electronic commerce using the wired network. The electronic authentication system technology based PKI was developed in order to guarantee the stability of this kind of the electronic commerce. but The effectiveness decreases because the mobile terminal makes the low capacity, and the low speed communication. In this paper, we propose the PKI security system using the agent server in consideration of the characteristic of the mobile terminal instead of the mobile authenticator. In the radio communication PKI system, by using CRL, and OCSP, this solves the problem that the realtime verification is impossible. At the same time with that, by minimizing the traffic of the mobile terminal the load of the terminal was minimized and the effectiveness at the mobile authentication stage was enhanced.
