Universally Composable and Forward Secure RFID Authentication and Key Exchange

Tri van Le, Mike Burmester, Breno de Medeiros

Abstract: Protocols proven secure in universally composable models remain secure under concurrent and modular composition, and may be easily plugged into more complex protocols without having their security re-assessed with each new use. Recently, a universally composable framework has been proposed for Radio-Frequency Identification (RFID) authentication protocols, that simultaneously provides for availability, anonymity, and authenticity. In this paper we extend that framework to support key-compromise and forward-security issues.

We also introduce new, provably secure, and highly practical protocols for anonymous authentication and key-exchange by RFID devices. The new protocols are lightweight, requiring only a pseudo-random bit generator. The new protocols satisfy forward-secure anonymity, authenticity, and availability requirements in the Universal Composability model. The proof exploits pseudo-randomness in the standard model.
