摘要： A communication apparatus obtains file information indicating all or a part of first and second encrypted pieces obtained by encrypting a plurality of pieces constituting a part of a content and version management information with which it is possible to judge whether the file information has validity and receives, for each of the pieces, one of the first encrypted piece and the second encrypted piece from another communication apparatus, by using the file information. The communication apparatus transmits, to a key server, a request message for requesting decryption keys each being used for decrypting the one of the first encrypted piece and the second encrypted piece received for a different one of the pieces and the version management information of the file information used to obtain the one of the first encrypted piece and the second encrypted piece in correspondence with each of the pieces and receives the decryption keys.

摘要： A communication apparatus stores encrypted pieces having plural pieces as a part of a content encrypted, and number of transmission times. At least one first piece is encrypted by plural different encryption keys. The communication apparatus selects as priority pieces plural encrypted pieces corresponding to at least one first piece among the first pieces, based on number of untransmitted encrypted pieces of which number of transmission times is zero among plural encrypted pieces of which first piece is encrypted, and stores priority piece information specifying the priority piece. When a piece request is received from other communication apparatus, the communication apparatus determines an encrypted piece to be transmitted, based on priority piece information, and transmits the encrypted piece to the other communication apparatus.

摘要： A scheme for realizing communications through an external network such as telephone network from a contents processing device such as AV device or PC connected to a local network such as home network is disclosed. The contents processing device solicits a set up of connection to the server device through the telephone network, to a gateway device which is connected with both the home network and the telephone network. Then, the gateway device carries out a call set up with respect to a specified address on the telephone network, upon receiving the solicitation from the contents processing device, and transfers data transmitted from the contents processing device to a connection established by the call set up, and data arriving from the connection established by the call set up to the contents processing device.
