    摘要: A masking operation method for a symmetric key encryption system includes, when at least two Substitution-boxes (S-boxes) are input, generating a masking S-box table for one S-box which was input; and performing an operation on one masking S-box by referring to the generated masking S-box table. Further, the masking operation method for the symmetric key encryption system includes performing an operation on a remaining masking S-box for a remaining S-box, which was input, by referring to the masking S-box table.

    摘要: Disclosed herein are a method and apparatus for generating a session key and a cluster key using a network coding scheme. The apparatus includes a random number generation unit, a combination generation unit, a combination transmission unit, a coding result reception unit, and a restoration unit. The random number generation unit generates the random number of a node. The combination generation unit generates a combination based on a master key of the node and the random number. The combination transmission unit transfers the combination to a key distribution server. The coding result reception unit receives a result of a network coding, corresponding to an ID of the node, from the key distribution server. The restoration unit for generating a session key by restoring a random number, corresponding to a counterpart node of the node, using the result of the network coding and the random number.

    摘要: An electronic tag for protecting privacy in RFID and a method of protecting privacy using the same are provided. Specifically, an RFID electronic tag capable of protecting privacy by authenticating an RFID reader and controlling access of the RFID reader to the RFID tag and a method of protecting privacy using the same are provided. The RFID electronic tag is applicable to a passive type RFID tag. The RFID electronic tag is also applicable to an ISO/IEC 18000-6 Type C tag that is a typical passive type RFID tag. It is possible to protect privacy of a user by controlling access of the RFID reader to the RFID tag and authenticating the RFID reader by modifying a tag inventory protocol and a memory map of the tag.
