An Improved Lightweight RFID Mutual-authentication Protocol

Abstract

Abstract. Aiming at the security problems and tag's cost problems of RFID, an improved light-weight RFID mutual-authentication protocol was proposed ,this protocol has proved to be save by BAN logic formal analysis method. Besides, Security analysis shows that the protocol possesses robust security as well as defending against malicious attacks such as disclosure attack, desynchronization attacks ,impersonation attack .It has better security and less consumption resource of computing and storage, etc.
