Authenticating method of communicating connection, gateway apparatus using authenticating method, and communication system using authenticating method

摘要

An authenticating method of communicating connection between a terminal and a gateway apparatus, the method including transmitting authentication information and first intrinsic identification information that is intrinsic identification information of the terminal from the terminal to the gateway apparatus and requesting the authentication; authenticating the communicating connection by using at least one of the first intrinsic identification information and the authentication information; and when the authenticating is successful, generating at least one authentication key by using at least one of the first intrinsic identification information and second intrinsic identification information that is intrinsic identification information of the gateway apparatus, thereby increasing communication security between the terminal and the gateway apparatus.
