Analysis and Improvement of Anonymous Authentication Protocol for Low-Cost RFID Systems

With the rapid growth of RFID applications, security has become an important issue. Security protocols work as a kernel for RFID technology. In this paper, we propose a serverless protocol to protect the system from suffering different type of attacks. Moreover, safety requirements for RFID protocols were analyzed, and a low-cost anonymous authentication protocol for RFID was proposed based on the universal composability mode. This protocol is feasible under a desynchronizing attack by recovering the disabled tags that are desynchronized with the reader because of this attack. The improvement of our scheme is the index item used for an advanced search. Finally, sufficient analysis is given to prove security quality of the protocol.
