Wireless communication and cloud are extremely popular because of its convenience, portability and immediacy. As the first line of defense for mobile communication with intelligent devices, identity authentication plays a more and more important role for system security and communication privacy. In order to enhance the security and privacy of wireless communication, this paper investigates an anonymous password-based remote user authentication and key exchange scheme for intelligent devices. Firstly, the scheme achieves secure mutual authentication while preserving user privacy. Secondly, client puzzle is employed to resist denial of service attacks and establish session keys with forward secrecy. Finally, the analysis demonstrate that our scheme works effectively and resists common known attacks, while maintaining the efficient performance for mobile users.
