    摘要: Methods and apparatus for efficient revocation of receivers. In one implementation, a method of broadcast encryption includes: assigning a respective master key to each of a plurality of receivers, where each master key can be used to derive two or more of a plurality of sub keys; revoking one or more receivers, leaving one or more unrevoked receivers; for each master key of an unrevoked receiver, selecting the sub key that can be derived by that master key and derived by the most other master keys but not derived by a master key of any of the one or more revoked receivers; for each selected sub key, encrypting one ciphertext using that selected sub key; and sending the encrypted ciphertexts to the plurality of receivers.

    摘要: A key generation device according to the present invention hierarchically constructs a Y-ary tree structure where n reception devices are assigned to leaves, and forms subgroups where individual intermediate nodes existing between the leaves and a root of the Y-ary tree structure are defined as parent nodes. By providing new parameters to the individual intermediate parameters, the subgroups can be formed flexibly. In a case where no excluded customer exists or the number of excluded customers is small, the size of a header to be delivered and the calculation amount of an operation that a customer needs to perform can be reduced.

    摘要: A user sends data for requesting a service provider to provide predetermined service and signature data created based upon the data to the service provider, the service provider calculates a fee based upon this data and requests a bank to collect the fee from the user. The bank informs the user of the fee requested from the service provider. When the user protests against the amount of the fee, the service provider discloses the data and signature data received from the user to the bank and when the bank judges based upon this signature data that this data is valid, it calculates a proper fee based upon this data and collects it from the user. As described above, it is enabled to collect a proper fee for service.

    摘要: Based on the detailed reproduction control information defining the reproduction control state of data to be transmitted, the CPU 12 of the data transmission apparatus creates a simplified reproduction control information roughly defining the reproduction control state of the data, stores the simplified reproduction control information of the data in the packet header of a data packet carrying the data, stores the detailed reproduction control information in the data, and transmits the simplified reproduction control information and the detailed reproduction control information as well as the data to the data receiving apparatus 20 through the transmission channel 30 from the input-output interface 16. The CPU 22 of the data receiving apparatus 20 analyses the reproduction control state of the data contained in the data packet based on the simplified reproduction information and the detailed reproduction information contained in the data packet, and controls the reproduction of the data by the action of the media access part 26 according to the analysis result.
