Abstract

We discuss insider attacks on RFID protocols with a focus on RFID tag privacy and demonstrate such attacks on published RFID protocols. In particular, we show attacks on a challenge-response protocol with IND-CCA1 encryption and on the randomized hashed GPS protocol. We then show that IND-CCA2 encryption can be used to prevent insider attacks and present a protocol secure against insider attacks. The protocol is based solely on elliptic-curve operations.
