RFID group verification method based on ecc

Abstract

The invention discloses an ECC-based RFID group verification method, which belongs to the technical field of group verification. The invention includes a system initialization phase, a reader authorization phase, a reader-writer and tag two-way authentication phase, a group certificate generation and a group certificate verification phase; the system initialization phase sets the communication keys of the server, the reader-writer and the tag; the reader-writer In the authorization phase, the verifier authorizes the reader to generate a group certificate; in the two-way authentication phase of the reader and tag, the mutual authentication between the reader and the tag is completed; in the group certificate generation and group certificate verification phases, the reader generates a group certificate based on the tag information. The proof is then verified by the verifier to verify the legality of the group's proof. The invention has strong privacy protection, untraceability, reader anonymity, tag anonymity, authorization authentication and other security aspects; and reduces the computational load of the tag during the interaction process, and adopts two-way authentication between the reader and the tag. , to prevent forgery attacks.

Description

technical field [0001] The invention relates to the technical field of group verification, in particular to an ECC-based RFID group verification method. Background technique [0002] Compared with barcodes, RFID technology has the advantages of non-contact, cheap, flexible deployment, easy management, and identifiable moving objects, and has gradually become one of the most popular technologies in automatic identification technology. [0003] The existing RFID single-tag identification authentication protocol has been widely used in supply chain management, automatic identification of people or objects, warehouse management, identification and other fields. In the rapid development and practical application of RFID, in some special occasions, the tags that need to be identified often have group characteristics, that is, two or more tags need to be scanned "simultaneously" within a certain range, and two or more tags must be provided. Evidence that tags were scanned by the s...
