Integrity Improvements to an RFID Privacy Protection Protocol for Anti-counterfeiting

摘要

The privacy problem of many RFID systems has been extensively studied. Yet integrity in RFID has not received as much attention as in regular computer systems. Some RFID applications require strong integrity as well as privacy, such as anti-counterfeiting, in which RFID tags axe used to authenticate items being tagged. In this paper, we propose an integrity model for RFID protocols. We then apply it to analyze integrity within the Squealing Euros protocol. a protocol for RFID enabled banknotes that supports lawful tracing and preserves individual's privacy. We then construct an improved protocol which provides integrity for the law enforcement, within a RFID privacy protection protocol for RFID enabled banknotes.
