Abstract
The Radio Frequency Identification(RFID) grouping-proof protocol is used to verify whether there are multiple tags,because in actual scenario,these tags are used for the identification of one object.However,due to the simple structure and limited computing and storage resources of the RFID tags,the security protocol is difficult to achieve.To address this problem,this paper proposes a grouping-proof protocol that insures privacy and forward security.First,this paper uses hash function and randomization to guarantee the confidentiality and privacy of each session.Then,by means of activate-sleep mechanism,filter-response mechanism and the combination of identity authentication and grouping-proof technology,the efficiency of protocol is improved.Analysis results show that the RFID grouping-proof protocol meets the requirements of anonymity and forward security,so it can prevent eavesdropping,tracking attack,replay attack and de-synchronize attack.
