Abstract:

In order to overcome the shortcoming in cryptographic protocols for radio frequency identification (RFID) using the backend database model, a lightweight authentication protocol for RFID was proposed without the need for a bakeend database based on the universally composable security model. The protocol provides anonymity, untraceability and mutual authentication. The implementation of the protocol requires only the use of pseudorandom function and has higher efficiency. Universally composable security guarantees that the protocol holds secure even when running in an arbitrary and unknown multiparty environment.

Key words: RFID system, authentication protocol, universal composition, model
