A fast handover authentication protocol takes an important role for delay-sensitive applications in wireless networks. Mobile users may be granted different priorities depending on communication fees they paid. In this paper, we present a priority-aware anonymous handover authentication protocol using attribute-based cryptography. The proposed protocol realizes mutual authentication, user anonymity, session key establishment and user revocation etc. Particularly it obtains a charming property, namely, user priority. Compared with some existing schemes, it is more efficient while satisfying security.
