    摘要: A terminal device 500 that is connected to a key distribution device 400 via a network, and in which a recording medium device 600 is mounted, the key distribution device 400 being for distributing a title key necessary for use of content, the recording medium device 600 being for storing therein the content and the title key. The recording medium device 600 and the key distribution device 400 perform mutual authentication and share shared keys that are identical to each other. The terminal device 500 comprises: a reception unit that receives an encrypted title key from the key distribution device 400, the encrypted title key being the title key encrypted with the shared key of the key distribution device 400; and a transfer unit 513 that transmits the encrypted title key to the recording medium device 600. Upon completion of the mutual authentication between the recording medium device 600 and the key distribution device 400, the reception unit and the transfer unit 513 refrain from any involvement with communication data except reception and transmission thereof, the communication data being exchanged between the recording medium device 600 and the key distribution device 400 with use of the shared keys.

    摘要: To provide a content playback device capable of protecting content according to DRM, when decrypting encrypted content recorded on a recording medium and playing the decrypted content. If key generation information is “00”, a key control unit 104 concatenates a decrypted media key and content information in this order, and applies a one-way function to the concatenation result to generate a content key. If the key generation information is “10”, the key control unit 104 sets a rights key as the content key. If the key generation information is “01”, the key control unit 104 concatenates the decrypted media key and the rights key in this order, and applies a one-way function to the concatenation result to generate the content key.

    摘要: An electronic money usage system is capable of preventing dishonest use of electronic money recorded on a recording medium. A memory card 300 acquires signature-type electronic data from a bank server apparatus 100, and generates a first authenticator using the received first authenticator, and an identification flag, an electronic money ID and an amount included in the electronic money. When a user uses the signature-type electronic money, the memory card 300 generates a second authenticator with use of a second password received from the user, and the identification flag, electronic money ID and amount included in the electronic money. The memory card 300 outputs the electronic money if the first authenticator and the second authenticator match.

    摘要: In an information input/output system, a user device inputs and outputs information to and from external sources including a key management device. The system includes the key management device that securely outputs invalid-device information specifying an invalid device unit that has been made invalid for use, and the user device that includes an input/output unit and a host unit. Via the input/output unit, input and output of information is enabled between the host unit and the external sources. The host unit securely receives, via the input/output unit, the invalid-device information outputted by the key management device and judges whether or not the input/output unit is an invalid device unit by referring to the received invalid-device information. When judging, that the input/output unit is an invalid device, the host unit thereafter prohibits input and output via the input/output unit. Due to this construction, the host unit can correctly judge whether or not the input/output unit is an invalid device unit.

    摘要: To provide a backup management device that deletes a content so as to be restorable in the future while protecting a copyright of the content, in a case where there exists a backup of the content. In an HD recorder 100, a first information storage unit 102 stores a content, a second information storage unit 103 stores a backup of the content, a secure storage unit 104 stores a hash value of the content. If receiving an instruction to delete the content so as to be restorable, a control unit 113 deletes the content from the first information storage unit 102. When the content is played back, an encryption processing unit 109 applies a calculation to the content to generate detection information, and the control unit 113 compares the hash value with the detection information to judge whether the content has been tampered.
