COMMUNICATION DEVICE, LSI, PROGRAM, AND COMMUNICATION SYSTEM

摘要

An object of the present invention is to prevent an attack from or via a communication device on an information apparatus in a communication system including the information apparatus, the communication device coupled to the information apparatus in the aftermarket, a server that authenticates the communication device, and a communication unit between the communication device and the server.;A communication device includes a first interface that performs first communications with a server, a second interface that performs second communications with an information apparatus, and an information processing unit that performs an information process including a communication protocol process accompanied by the first and second communications. The information processing unit of the communication device sends a signature of the communication device from the first interface to the server, receives via the first interface a driver sent after the server authenticates the communication device on the basis of the received signature, and sends the received driver from the second interface to the information apparatus.

主权项

1. A communication device comprising a first interface that performs first communications with a server, a second interface that performs second communications with an information apparatus, and an information processing unit that performs an information process including a communication protocol process accompanied by the first and second communications,
wherein the information processing unit sends a signature of the communication device from the first interface to the server, receives via the first interface a driver sent after the server authenticates the communication device on the basis of the signature, and sends the received driver from the second interface to the information apparatus, and wherein the driver is software that is installed in the information apparatus to allow the information apparatus to cooperate with the communication device.
