A SECURE AND EFFICIENT METHOD AND RFID READER DEVICE OF SEARCHING A RFID TAG
摘要
PURPOSE: A safe and effective RFID(Radio Frequency Identification) tag searching method and RFID reader apparatus are provided to prevent a message playback attack by using an XOR calculation method and a hash calculation method. CONSTITUTION: A memory unit(11) stores total authentication information and individual authentication information. The total authentication information is related to the encryption key of tags. The individual authentication information is related to a first authentication value. A control unit(12) creates the first authentication value from the individual authentication information of a search tag and creates a second authentication value by calculating the total authentication information and a first counter. The control unit transmits the first and the second authentication value to the tag, compares a second counter received from the tag with the first counter, and authenticates the searching tag.
