| Abstract: | In this paper, a novel authentication protocol based on CDMA and Hash function is presented. The new protocol can tackle with the problem of tag collisions and resist several possible attacks, including reply, tracking, blocking, proofing, and inner attacks. Both theory and analysis show that the new protocol, compared with other authentication protocols, improves the security of RFID systems effectively and does not increase the complexity of protocol. |
