A New Hash-Based Authentication Protocol for RFID Using Varying Identifiers

Abstract

This article proposed a new security protocol with satisfying the lightweight requirements of the security of RFID system. Using varying identifiers, the protocol can resist Forward attack, Traffic analysis and Tracking attack, Replay attack. The Back-end Server holds the new identifier and last identifier for every Tag can keep database synchronization. Each Tag store a unique Key that is the secret information which also store in the Back-end Server. Use the Key, the protocol can implement mutual authentication between Back-end Server and Tag. Then the paper compared the proposed protocol with the typical protocols in security, effective and cost. The results demonstrate that the protocol can effectively solve the security problem of RFID systems.
