Abstract: A node identifier generation method in a tree structure is provided to enable each communication device to first analyze padding information when analyzing node identifiers included in destination addresses of received packets, thereby easily deciding on locations of nodes within a tree structure, consequently communication of the communication devices can be very efficiently processed. A location information storage(512) stores location information on a path reaching up to a target node from a root node of a tree. A padding information storage(514) stores padding information which includes depth information and a padding code of the target node. The location information is generated by sequentially allocating branch identifiers assigned in every branch up to the target node from the root node. The padding information is generated by inserting the padding code selected from values except a group identifier of the target node, as much as the depth information. A receiver(520) that consist of an index receiver(522) and a data receiver(524) receives a packet, which includes index information and data, from transmitters of other nodes that belong to a tree structure. A controller(530) compares a destination address included in the index information with the information stored at a node identifier storage(510).

Abstract: A method and a system for encrypting an RF-ID(Radio-Frequency-Identification) tag using a broadcast encryption type are provided to improve convenience of a user by inhibiting an arbitrary attacker from performing an access-lock for the RF-ID tag. In a system(100) for encrypting an RF-ID tag(120) using a broadcast encryption type, an ID(identification) of the RF-ID tag(120) is encrypted. An index, a header, and the encrypted ID are generated and stored in an inner storage according to information from readers(131-137). The readers(131-137) are allowed to read the RF-ID tag(120). The encrypted ID is stored in the RF-ID tag(120) to distribute. When the encrypted ID is received from the arbitrary reader(131-137), the index and the header corresponding to the received encrypted ID are transmitted to the corresponding reader(131-137).

Abstract: A method for assigning a content playback right to an offline video device through a recording medium is provided to enable the offline video device to play the contents stored in the recording medium and requesting the playback right for playback by assigning the playback right to the offline video device through the recording medium. An encoded key is recorded to the recording medium. The contents encoded by the key are recorded to the recording medium. Information for the playback right to play the contents recorded in the recording medium is recorded to the recording medium(S360). The playback right includes the information for the video device receiving the playback right. The video device determines whether the playback right is permitted or not by referring to the permitted video device information included in the playback right recorded in the recording medium. If the video device corresponds to the permitted video device, the video device decodes and plays the encoded contents recorded in the recording medium.
