摘要: In an RFID-enabled supply chain, where items are outfitted with RFID tags, path authentication based on tag enables the destination checkpoints to validate route that a has already accessed. this work, we propose novel, efficient, privacy-preserving system for chains. Compared existing Elliptic curve Elgamal Re-encryption (ECElgamal) solution, our Homomorphic Message Code arithmetic circuit (HomMAC) solution offers less memory storage (with limited scalability) and no computational requirement reader. However, unlike previous schemes, allow ability inside consents new privacy direction proposed by Cai et al. in ACNS012. addition, customize polynomial-based scheme (to thwart potential impersonation Denial of Service (DoS) attacks), so it fits protocol.
