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.

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.

Provided are a method for passive radio frequency identification (RFID) security according to a security mode. An RFID tag transmits its own current security mode to a reader and the reader drives a security protocol depending on the current security mode of the RFID tag. Also, the reader grasps the ability of the tag and then the reader drive a protocol suitable for the ability through the security mode.

An apparatus for generating a secret key generates the secret key by using information of a mobile RFID terminal, transmits the generated secret key to an RFID tag attached on an article, and decrypts a unique item identifier of the article encrypted by using the generated secret key after receiving the unique item identifier of the article encrypted by using the secret key from the RFID tag. By this configuration, it is possible to protect user's personal privacy of the mobile RFID terminal in a state where user's intervention is minimized.

Disclosed are a radio frequency identification (RFID) security apparatus and a method thereof. According to the RFID security method, a secure tag reader performs determining an AES key using security information received from a secure tag and generating an output key using the determined AES key, decrypting AES data received from the secure tag using the output key, and encrypting data to be transmitted to the secure tag using the output key and transmitting the data, and a secure tag performs generating an output key using an AES key and security information, and transmitting the security information to a secure tag reader, encrypting data to be transmitted to the secure tag reader using the output key, and transmitting the encrypted data to the secure tag reader, and decrypting data received from the secure tag reader using the output key.
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.
