摘要： A certificate validation method for causing a certificate validation server to receive a certificate validation request from a given terminal device, build a certification path of from a first certificate authority (CA) to a second CA, perform validation of the certification path, and send a validation result to the terminal which issued the certificate validation request is disclosed. The validation server detects either a key update of any given CA or a compromise of the given CA, acquires a certificate of relevant CA and first certificate status information and second certificate status information, stores the acquired information in a storage unit or, alternatively, updates the information stored in the storage based on the acquired information, and performs the building of a certification path and validation of the certification path by use of the information of the storage unit.

摘要： The validation server obtains information related to a first cryptographic method from a certificate which is contained in a certificate validation request from a terminal device. When the information related to the first cryptographic method is not stored in a storage unit of the validation server as valid information, the validation server determines that the information related to the first cryptographic method is invalid. When the information related to the first cryptographic method is stored in the storage unit as valid information and also the information related to a second cryptographic method listed in the certificate in the certification path is not stored in the storage unit during the certification path validation, the validation server determines that the information related to the second cryptographic method is invalid.
