Abstract
A first authentication apparatus obtains a modification restriction parameter which is stored in a second authentication apparatus and which indicates a number of times a mutual authentication pair modification is possible or a number of times modification has been executed. The first authentication apparatus transmits to the second authentication apparatus authentication information corresponding to the modification restriction parameter. The second authentication apparatus receives the authentication information from the first authentication apparatus. The second authentication apparatus determines whether or not the received authentication information is authentication information for permitting the mutual authentication pair modification. In a case where the received authentication information is authentication information that permits the mutual authentication pair modification, the second authentication apparatus and the first authentication apparatus form a mutual authentication pair.
