RFID grouping-proof protocols draw high attention as RFID technology is being widely applied. This paper proposes an improved ECC-based grouping-proof protocol on the basis of studying the grouping-proof protocol proposed by Batina et al. to solve the problems of existing grouping-proof protocols, such as low grouping-proof efficiency and being vulnerable to impersonation attacks, tracking attacks, and other security threats. First of all, this paper proved that the protocol by Batina et al. is vulnerable to impersonation attacks and tracking attacks. Secondly, the proposed improved groupingproof protocol was described and analyzed. Malicious query of tags has been prevented because a new function of reader verification by tags is added to the existing protocols. Finally, the security performance of the proposed protocol was proved and a comparison with the protocols proposed in the references was made. As the theoretical analysis and comparison reveal, the scheme, with a significantly enhanced security and performance compared with similar schemes, meets the requirements for security and privacy.
