摘要： PROBLEM TO BE SOLVED: To provide a communication technique for controlling illegal decoding of the encrypted contents even if a bunch of keys including each decoding key for decoding the encrypted contents is disclosed in a contents distribution system. SOLUTION: A contents acquisition part 500 receives each encrypting piece composing contents to be encrypted from at least one of seeders. Moreover, this contents acquisition part 500 decides whether the encrypting piece acquired is an invalid encrypting piece by referring to an invalid piece list acquired by an invalid piece list acquisition part 504. This contents acquisition part 500 further deletes the relevant encrypting piece and acquires an alternative encrypting piece of the relevant encrypting piece when the encrypting piece acquired is decided as the invalid encrypting piece. The invalid piece list acquisition part 504 acquires the invalid piece list from a tracker. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide communication technologies which uniquely determine a combination of each encrypted piece for each communication device which is distributed in a content distribution system, and to improve the flexibility of system build up.
SOLUTION: When a node ID sequence is received, a random number sequence and encrypted pieces from other nodes 50 and 51, a node 51 links and stores them in an associated manner. If a piece request is received from the other node 51, the node 51 generates a temporary symmetric key using a random number and a secret key, determines encrypted parts that are some parts of the encrypted pieces, and additionally encrypts the encrypted parts using the temporary symmetric key. Then, the node 51 transmits own node ID, to the other node 51, together with: the node ID sequence that is linked to the encrypted pieces and stored; a random number generated by itself with the random number sequence that is linked to the encrypted pieces and stored; and newly encrypted pieces that some of them are encrypted by itself.
