Abstract: PROBLEM TO BE SOLVED: To make it possible to surely trace a certificate for one certification association(CA) which was issued by another CA from a certificate of the former CA which perform mutual authentication by including a process that confirms matching of an object public key. SOLUTION: An object key is taken out from a certificate of one CA out of two CAs performing mutual authentication and this is called X1. Next, in processing 2, an object public key is taken out from a certificate which was issued by a mutually authenticating CA for the former CA and this is called Y1. Then, in a judgment 3, if the object public keys match (X1=Y1), it means that the certificate for one CA which the CA of the mutually authenticating party has issued can be traced from the certificate of the former CA and so the processing is regarded as successful. Also, in the judgment 3, if X1≠Y1, it means that the certificate for one CA which the CA of the mutually authenticating party cannot be traced from the certificate of the former CA and so the processing is regarded as a failure.
