Aiming at the issues of the existing RFID grouping-proof protocol in security and privacy, an ECC-based RFIDgrouping-proof protocol is proposed based on the privacy model and the identification protocol proposed by Jens Hermans.This article describes the proposed grouping-proof protocol and demonstrates in correctness, soundness and privacy.The result of theoretical analysis indicates that this scheme meets the requirements of correctness, soundness and privacy,and compared with the similar schemes, this scheme has the higher efficiency. This protocol is low in cost, secureand scalable, and has a certain practicability.
