A security and privacy model for mobile RFID systems in the internet of things

For the security and privacy of mobile radio frequency identification (RFID) systems in the internet of things, a novel security and privacy model is proposed in this paper. The model not only takes into account the privacy of tags and readers, but also supports tag corruption, reader corruption, multiple readers and mutual authenticated key exchange (AKE) protocols. We then propose a new AKE protocol for mobile RFID systems. Security analysis shows that the protocol is correct, secure and tag-forward private in our model. Furthermore, our protocol is efficient in terms of computation, communication rounds and functions.
