Abstract: PURPOSE: A method for passive RFID security according to a security mode is provided to drive security protocol according to a current security mode of the RFID tag after the RFID tag transfers the current security mode to a reader. CONSTITUTION: If the first random number, protocol control information, extended protocol control information and unique item identification information is received form a RFID(Radio Frequency Identification System) tag, the RFID reader requests the second random number(S140,S150). If the second number is received from the tag, the reader requests a security parameter(S170,S180). If an encrypted data is received from the tag, the reader requests encrypted data authentication result to a authentication server(S220,S230). The authentication server authenticates the tag(S240).
