Forward Secure Privacy Protection Scheme for RFID System Using Advanced Encryption Standard

摘要

There are many researches related to privacy protection in RFID system. Among them, Ohkubo's hash-based scheme is provably secure and it can protect user's privacy, prevent location tracking, and guarantee forward security completely. Unfortunately, one-way hash functions, which play important roles in Ohkubo's schem, can't be implemented into the current RFID tag hardware. So we propose a new secure protocol for RFID privacy protection, and it is a modified version of Ohkubo's scheme using Feldhofer's AES module for RFID tag. Our new scheme has almost all of advantages of Ohkubo's scheme and moreover it can be embedded into RFID tag hardware easily.
