Title: strong privacy for RFID systems from plaintext-aware encryption

Abstract: in this talk we briefly survey the evolution of privacy protection in RFID protocols, then the model I presented at Asiacrypt'07. In this model, the strongest notion was proven to be impossible to achieve. Then, several relaxations were proposed. We finally change a bit the definition and show that strong privacy is feasible based on plaintext-aware encryption.
