RELAY APPARATUS, TERMINAL APPARATUS, AND COMMUNICATION METHOD

摘要

In a communication system in which a relay apparatus, a terminal apparatus, and other apparatuses, which can communicate with an authentication apparatus, are coupled through a communication path, the relay apparatus, and the terminal apparatus have unique authentication information, respectively. The relay apparatus transmits its own authentication information and authentication information collected from the terminal apparatus to the authentication apparatus. The authentication apparatus determines whether the relay apparatus and the terminal apparatus are authentic apparatuses based on the received authentication information. The relay apparatus shuts down communication between itself and an apparatus determined to be unauthentic based on a result of the determination, and transmits communication control information to shut down communication with the apparatus determined to be unauthentic to the terminal apparatus. The terminal apparatus shuts down the communication between itself and the apparatus determined to be unauthentic based on the communication control information.

主权项

1. A relay apparatus which can communicate with an authentication apparatus and can be coupled to a communication path to which other apparatuses are coupled,
wherein the relay apparatus and the other apparatuses respectively have unique authentication information, wherein the authentication apparatus has a function of apparatus authentication that determines whether or not the relay apparatus and the other apparatuses are authentic apparatuses based on the authentication information, and wherein the relay apparatus transmits its own authentication information to the authentication apparatus, collects authentication information from the other apparatuses coupled to the communication path and transmits the authentication information to the authentication apparatus, receives a result of the apparatus authentication from the authentication apparatus, shuts down communication between itself and an apparatus determined to be unauthentic based on the result, and transmits communication control information to the other apparatuses to shut down communication with the apparatus determined to be unauthentic.
