Improved Secure Lightweight RFID Authentication Protocol

Abstract

In order to improve the computing performance and security of RFID authentication protocol, an improved lightweight RFID two-way authentication protocol is proposed. With the authorization of a small amount of additional information, the two-way authentication between the reader and the tag can be completed quickly, without the need to communicate with the backend server frequently, which avoids increasing the security risks and communication costs caused by additional communication. Compared with the existing RFID authentication protocol, the improved protocol has meet requirements of backward security, mutual authentication, synchronization and non-denial of service. The improved protocol is suitable to be deployed in mobile RFID environment and applied in low-cost RFID tags.
