Cryptanalysis and Improvement of a New Ultra-lightweight RFID Authentication Protocol with Permutation

The security of RFID systems is a very important issue in the applications of RFID systems. Developing of authentication protocols is a general solution to * Corresponding author: e-mail: [email protected] (Eun-Jun Yoon) 3434 Il-Soo Jeon and Eun-Jun Yoon resist security attacks. However, since low-cost RFID tags have very limited hardware resources, it is not easy to develop an authentication protocol to resist the security and privacy attacks. This paper proposes an efficient ultra-lightweight RFID authentication (EURFID) protocol for low-cost RFID tags in order to reduce hardware resource requirement on the tags, each tag uses only two operations: XOR and separation operations.
