摘要： A communication apparatus receives, from another communication apparatus, a plurality of encrypted pieces obtained by encrypting a plurality of pieces constituting a part of a content and obtains a part or all of decryption keys used for decrypting the encrypted pieces. The communication apparatus also obtains an invalid piece list showing one or more identifiers of one or more encrypted pieces that can respectively be decrypted by using one or more decryption keys that have already been invalidated. In the case where at least one of the encrypted pieces is listed in the invalid piece list, the communication apparatus deletes the at least one of the encrypted pieces, based on an obtainment status of the encrypted pieces or an obtainment status of 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.
