Abstract
A communication apparatus sends a processing request, including request information, a digital signature, and an electronic certificate, to a control apparatus. The control apparatus sends a verification request including the electronic certificate to a verification server. The verification server verifies the electronic certificate included in the verification request, and sends authentication-use reference information, including the verification result, as a verification response, to the control apparatus. When the verification result included in the authentication-use reference information indicates validity, the control apparatus, using the request information and a public key included in the electronic certificate, verifies whether or not the digital signature is valid. When the digital signature is valid, the control apparatus performs the requested processing in accordance with the request information, and sends a processing response, to the communication apparatus.
