METHOD FOR TRANSMITTING ACCESS POLICY BETWEEN ROUTERS BY USING IDENTITY

摘要

PURPOSE: A method for transmitting an access policy between routers by using identity is provided to correlate identity information as a public key with a personal key corresponding to the information by introducing a public key concept, thereby remarkably reducing calculations and transmissions without session keys. CONSTITUTION: An extension initializer(10) transmits a message to a policy manager(12)(S51). The policy manager(12) transmits a response message to the extension initializer(10)(S52). The extension initializer(10) transmits an encoded message, which is identity of a target router(11), to the target router(11)(S53). The target router(11) decodes the received message with a personal key, confirms an extension code and a policy, and transmits an encoded confirm message to the extension initializer(10) in order to inform the extension initializer(10) whether an extension is successfully installed(S54).
