摘要： A download control program of a client terminal transmits a request to a download server, which stores Download Descriptors that include attribution information of contents, for a Download Descriptor, and receives the Download Descriptor from the download server. The download server, before transmitting the Download Descriptor to the client terminal, adds information indicating that there is a difference between a Download Descriptor contained in the request from the client terminal and the Download Descriptor stored in data memory of the download server if the download server detects the difference between them. The client terminal transmits a content download request to a contents server based on the received Download Descriptor.

摘要： A portable terminal MA downloads a content from a content server and stores the content in a HDD of the portable terminal after encrypting the content key with a terminal bind information which is inherent to the portable terminal. After that, when the portable terminal backs up the downloaded content to a personal computer, the portable terminal decrypts the content key with the terminal bind information and encrypts the content with a telephone number information. On the contrary, when the portable terminal restores the backed up content from the personal computer, the portable terminal decrypts the encrypted content key with telephone number bind information and encrypts the content with the terminal bind or new terminal information.
摘要翻译：便携式终端MA从内容服务器下载内容，并且利用便携式终端固有的终端绑定信息对内容密钥加密之后，将内容存储在便携式终端的HDD中。之后，当便携式终端将下载的内容备份到个人计算机时，便携式终端利用终端绑定信息来解密内容密钥，并利用电话号码信息加密该内容。相反，当便携式终端从个人计算机恢复备份的内容时，便携式终端用电话号码绑定信息解密加密的内容密钥，并利用终端绑定或新的终端信息加密内容。

摘要： According to one embodiment, a host computer updates the media key block MKB in a first updatable memory device in the case where the version number of the media key block MKB read from a recording medium is newer than that of the media key block MKB in the first updatable memory device. The host computer generates a medium unique key Kmu based on a media key Km calculated from the media key block MKB read from the recording medium and a media ID read from the recording medium. The host computer executes the authentication and key exchange AKE process with the recording medium based on the medium unique key Kmu.
