The invention discloses a wireless ultrahigh-frequency radio-frequency identification system and a method thereof for resisting invalid quantity statistical attack. The system stores a label sequence number TID and a current communication sequence number SID in a reader and an electronic label, the reader expresses validity by using a random number Rn and the current communication sequence number SID through a cipher text h (Rn, SID) combined by a unidirectional hash function h (x1, x2), and the electronic label only responds to the reader message with accurate cipher text; the reader uses an encrypted communication sequence number as signature when sending commands to the electronic label, and the label verifies the validity of the reader by checking the received signature; and after receiving the search request of the valid reader, the electronic label proves self valid identify by sending the message containing the encrypted label sequence number. The method invalidates the invalid electronic label quantity statistical attack, and meanwhile protects the security of electronic label personal communication realized as common security protocols.
Description
technical field [0001] The invention relates to a wireless ultra-high frequency radio frequency identification system, in particular to a method for ensuring safe communication of the wireless ultra high frequency radio frequency identification system, especially resisting illegal quantity statistics attacks. Background technique [0002] Wireless UHF radio frequency identification technology (Radio Frequency Identification) is an advanced non-contact automatic identification technology, which has great application potential and broad prospects in retail, logistics and other industries and fields. Compared with traditional non-contact identification technology, radio frequency identification has the advantages of long distance, high accuracy, low cost, and no need for direct optical docking communication. [0003] At present, the commonly used radio frequency identification communication protocols in the world include EPC CLASS 1 GEN 2 and ISO-18000-6C. The corresponding pro...
