A New Privacy-preserving Path Authentication Scheme using RFID for Supply Chain Management

초록

This paper presents a privacy-preserving path-authentication method for supply chain management using RFID. Compared with previous works, our scheme employs only symmetric encryption and message authentication codes. This reduces computation and communication overhead. The proposed method also supports high-level privacy without the need for tamper-proof tags as compared with the previous methods. Performance analysis demonstrates that the proposed scheme requires far less computation resource than recent works, proving that less than 1 minute is enough to verify 100000 RFIDs in a conventional reader environment.
