Abstract
An examination apparatus includes a receiving part, an acquisition part, and an examination part. The receiving part receives a public key certificate and identification information of the communication device from the device, which conduct the authentication process by using the public key encryption and sends the public key certificate used for the authentication process only to a specific communication partner. The acquisition part acquires information showing the public key certificate corresponding to the identification information, from a location other than the device based on the identification information. And, the examination part examines the device based on whether or not the public key certificate received by the receiving part is proper, by referring to the information acquired by the acquisition part.
