    摘要： A tag generation method for generating tags used in data packets in a broadcast encryption system is provided. The method includes detecting at least one revoked leaf node; setting a node identification (node ID) assigned to at least one node among nodes assigned node IDs at a layer 0 and to which the at least one revoked leaf node is subordinate, to a node path identification (NPID) of the at least one revoked leaf node at the layer 0; generating a tag list in the layer 0 by combining the NPID of each of the at least one revoked leaf nodes at the layer 0 in order of increment of node IDs of the corresponding at least one revoked leaf nodes; and generating a tag list in a lowest layer by repeatedly performing the setting and generation operation down to the lowest layer.

    摘要： A security method using an electronic signature, which improves the performance of an electronic signature authentication by generating and verifying an electronic signature using a mediator, and acquires a forward security in an electronic signature generation and verification by adding a forward secure signature of semi-trusted party (SEM) to a partial signature value generated based on a secret key piece of the SEM. A public key and an optional secret key composed of two kinds of pieces are generated by a certificate authority in response to a request from a user terminal device. The secret key pieces are issued to the user terminal device and a semi-trusted party not to be overlapped with each other. A first signature piece generated from the issued pieces of the private key is transmitted to the user terminal device from the semi-trusted party when a certificate of the user terminal device is still valid.

    摘要： A radio frequency identification (RFID) tag encryption method and system using a broadcast encryption (BE) scheme are provided by encrypting an ID of an RFID tag, storing the encrypted ID in a server and the RFID tag, and storing information relating to a reader authorized to read out the RFID tag in the server so that the reader can read out the RFID tag by decrypting the encrypted ID based on the encrypted ID information read from the RFID tag and the reader information. When readers read out ID data from the RFID tag, a privileged reader can read the data. Thus, it is possible to block unintended information leakage to the readers. In addition, user usability can be enhanced since an attacker cannot perform an access lock on the RFID tag.
