摘要： A license server (10) includes a CRL database (306) holding a revocation list recording therein classes predetermined corresponding respectively to a memory device, such as a memory card, and a content reproduction circuit, such as a cellular phone, that are subjected to revocation of distributing, reproducing and transferring content data. A distribution control unit (315) suspends an operation distributing content data if the distribution is addressed to a class listed on the revocation list. The revocation list is also held in the memory card and distribution control unit (315) in distributing content also transmits information for updating the revocation list in the memory card.

摘要： The present invention provides a technique for improving the convenience of the user while protecting the copyright of contents. A device receives contents usage right information from a storage device, and decrypts encrypted contents data using a contents key contained in the contents usage right information thus received. At this time, the device stores status information which indicates the use state of the contents usage right information. Furthermore, the device measures elapsed time for decryption of the encrypted contents data using the contents key, or elapsed time for reproduction of the contents data decrypted using the contents key. The device determines whether or not the contents usage right information has been used, based upon the elapsed time thus measured. Then, the device updates the status information stored in a log storage device, based upon the determination result.

摘要： Confidential data such as license data is encrypted using the symmetric key encryption algorithm alone which requires smaller computation amount, and is readily realized by hardware means, as compared with the public key encryption algorithm. A license-data transmitter (y) encrypts license data LIC using two keys Kscy and Kssx supplied from a license-data receiver (x). The license data is provided to the license-data receiver in the form of encrypted license data E(Kscy, E(Kssx, LIC)). This enables high-speed processing without deterioration in security even if data access such as recording/readout of data is repeated.

摘要： An object of the present invention is to provide a catalyst-coated membrane suitable for achieving a polymer electrolyte fuel cell that sufficiently prevents a decrease in the initial characteristics and also exhibits sufficient cell performance for a long period of time and has excellent durability. In at least the cathode catalyst layer, the ratio (WP/WCat-C) of the weight of the polymer electrolyte (WP) to the weight of the catalyst-carrying carbon (WCat-C) is decreased from an innermost layer positioned closest to the polymer electrolyte membrane toward an outermost layer positioned farthest from the polymer electrolyte membrane. The ratio (WP/WCat-C) in the innermost layer is 0.8 to 3.0, and the ratio (WP/WCat-C) in the outermost layer is 0.2 to 0.6.

摘要： An object of the present invention is to realize an in-home network system that is capable of smoothly controlling an appliance even when a new kind of appliance that has not been obtained conventionally is connected to an in-home network or even when an unusual, special use form is set in a network. A controller of the present invention compares a device type of an appliance connected to an in-home network with a skeleton stored in a skeleton DB. When a skeleton rule in accordance with the appliance type is not stored in the skeleton DB, a request for acquisition of the skeleton rule of the appliance is transmitted to a service agent. In addition, when the location of an appliance is moved, the controller sends a request for transmission of a new rule format to be added due to the movement to the service agent.
