| abstract | Kind Code: A1 An attribute certificate authority does not pass a secret key for signature generation to another authority, does not make a issued certificate disposable, and further associates attribute certificates generated from certain original data. Generate an attribute certificate that cannot be removed. [Solution] The attribute certification seed storage unit 505 associates each partial electronic signature data generated using a secret key with each attribute data for each hash value obtained by calculating each of a plurality of attribute data with a hash function. Save the attribute certification seed that consists of all the attached groups. The random number generation unit 506 generates a different random number for each attribute data, the attribute certificate generation unit 507 conceals the attribute data to be concealed with the corresponding random number, and each partial electronic signature, each random number, Electronic signature data is generated based on the public key. Then, the attribute certificate transmission unit 508 transmits the data that conceals the attribute data, the attribute data that is not concealed, and the electronic signature as the attribute certificate.
