摘要： Each of the embodiments of the present invention relieves a service provider of the burden of managing personal information. A group administration organization device 10 admits a user device to an authorized group by request and sends authority permission information to the user device 20. The user device 20 holds the authority permission information received from the group administration organization device 10 and, on access, sends authority proof information created from the authority permission information using a group signature scheme to a service provider device 30 as requested by it. The service provider device 30, upon being accessed, requests the authority proof information and verifies the authority proof information received from the user device in accordance with the request on the basis of the group signature scheme. When the verification result indicates validity, the service provider device provides a service. Thus, there is no need for the service provider to manage personal information of the user because the user device proves to the service provider device using the group signature scheme that it belongs to the authorized group.

摘要： Each embodiment of this invention implements step-by-step and empirical authentication of devices upon digital authentication among a plurality of devices. Each of a plurality of authentication devices of each embodiment can unidirectionally generate a hash value of a low experience rank from a hash value of a high experience rank, and receives a set of high experience rank and hash value in accordance with an experience. Upon receiving a certification request of the experience rank from another authentication device, the authentication device transmits a corresponding hash value to the authentication device as a request source. Upon sending a certification request of an experience rank to another authentication device, the authentication device verifies a hash value obtained from the other authentication device on the basis of a self hash value. In this way, the authentication devices authenticate each other's experience ranks.

摘要： A source of MPEG2 video data is connected with a dedicated AV device or personal computer by means of an IEEE 1394 interface. A transmission unit in the source has an IEEE 1394 encryption unit and a sending I/F unit. A reception unit varies between the dedicated AV unit and the personal computer. In the reception unit of the dedicated AV device, a receiving I/F unit and a decryptor are integrally incorporated into one semiconductor chip and an MPEG2 decoder is incorporated into one semiconductor chip. In the reception unit of the personal computer, the receiving I/F unit is formed of one semiconductor chip, and the decryptor connected to the I/F unit through a bus, and the MPEG2 decoder are formed of one semiconductor chip. Thus, data before decryption will not appear on the bus, which prevents MPEG2 video data from being taken out of the computer for illegal copying purposes. In addition, the reception unit is made to have a different physical configuration depending on whether it is to be mounted in the dedicated AV device or the personal computer. This will prevent the reception unit (including the decryptor) of the dedicated AV device from being connected in the personal computer in place of its associated reception unit (excluding the decryptor).

摘要翻译： MPEG2视频数据源通过IEEE 1394接口与专用AV设备或个人计算机连接。 源中的传输单元具有IEEE 1394加密单元和发送I / F单元。 接收单元在专用AV单元和个人计算机之间变化。 在专用AV设备的接收单元中，一个接收I / F单元和解密器被整合在一个半导体芯片中，并且MPEG2解码器被并入到一个半导体芯片中。 在个人计算机的接收单元中，接收I / F单元由一个半导体芯片形成，并且解码器通过总线连接到I / F单元，并且MPEG2解码器由一个半导体芯片形成。 因此，解密之后的数据不会出现在总线上，这样就不会将MPEG2视频数据从计算机中取出来进行非法复制。 此外，接收单元根据是否要安装在专用AV设备或个人计算机中而具有不同的物理配置。 这将防止专用AV设备的接收单元（包括解密器）代替其关联的接收单元（不包括解密器）连接在个人计算机中。

摘要： A purchaser apparatus stores “anonymous order information including an order ID and purchaser identity verifying information” and “purchaser identity proving secret information”. A shop apparatus stores “anonymous order information including an order ID and purchaser identity verifying information”. If necessary, a purchaser sends a request including an order ID and zero knowledge proving information that a purchaser knows the purchaser identity proving secret information, from a purchaser apparatus to a shop apparatus. A shop apparatus verifies the zero knowledge proving information, based on purchaser identity verifying information retrieved from an order ID included in the request. Therefore, the unlinkability for past use is eliminated if necessary, and inconvenience caused by the unlinkability is eliminated.
