People's desire for more convenient life and more efficient collaboration may be coming true in this era. Meanwhile there are lots of security challenges in wireless mobile networks. To resist conventional attacks and obtain stronger securities in the scenarios of mobile emergency services, we propose a privacy-preserving authenticated key agreement protocol with smart cards which requires no verification tables stored by the server and provides both perfect forward security and user anonymity. Emergency notifications are modeled as emergency message codes that are provided with security and anonymity by the protocol.
