摘要
According to an embodiment of the present invention, an issue system previously issues a smart card, and sends an encrypted private key and a public key certificate to a user terminal, when issuing a new card or updating an old card. A user terminal inputs the received encrypted private key and public key certificate into a smart card. A smart card stores a public key certificate, and decrypts the inputted encrypted private key by an encryptor/decryptor based on a symmetric key, and stores the obtained private key. Therefore, collection and redistribution of a smart card becomes unnecessary, when updating a private key and a public key certificate, saving the time and labor.
