摘要： A terminal writes first encrypted data in which a communication key and an owner ID are encrypted by using a public key into a second recording medium, and this medium is mounted to a communication apparatus so that the first encrypted data are transmitted to a server. The server sends second encrypted data which it acquires by encrypting a content decryption key by using the communication key which the server acquires by decrypting the received first encrypted data by using a secret key to the communication apparatus, and causes the communication apparatus to record them into the second recording medium. The terminal decrypts a content stored in a first recording medium by using the content decryption key which it acquires by decrypting the second encrypted data read from the second recording medium by using the communication key.
摘要翻译： 终端通过使用公钥将通信密钥和所有者ID加密的第一加密数据写入第二记录介质，并且将该介质安装到通信装置，使得第一加密数据被发送到服务器。 服务器通过使用服务器通过使用秘密密钥对接收的第一加密数据进行解密而获取的通信密钥来加密内容解密密钥来发送其获取的第二加密数据，并使通信装置将其记录到 第二记录介质。 终端通过使用通过使用通信密钥对从第二记录介质读取的第二加密数据进行解密而获得的内容解密密钥来解密存储在第一记录介质中的内容。
