摘要
A memory card includes a storage unit storing key information and version information in association with the key information, the key information and the version information being issued by a key issuing authority and the version information indicating a version of the latest revocation list that has been issued when the key information is generated. A revocation list receiving unit receives a revocation list having a version; and a version verification unit compares the version of the revocation list received by the revocation list receiving unit and the version information. When the version of the revocation list is older than version information, processing by a revocation list writing unit is prohibited.
