ABSTRACT:
A method and system for authenticating between a user or client and a network access entity such as a server or another client using an IC card. The method includes a step of executing an initial authentication using the IC card when the user first communicates with the network access entity, a step of commonly holding authentication information in both the user and the network access entity if the initial authentication achieves success, and a step of executing a re-authentication using the commonly held authentication information without using the IC card when the user communicates again with the same network access entity within a predetermined period of time after the last authentication.
