User Authentication Protocol Based On Chebyshev Polynomial For Wireless Sensor Networks

Aiming at the security problem of external users access to the wireless sensor networks, a new user authentication protocol with a key exchange function under the public-key system was proposed, the protocol based on the Chebyshev polynomials over finite fields have good chaos characteristic, semi-group property and the one-way trapped characteristic. This protocol can achieve the authentication process between user and network base station or sensor nodes, and completes the initialization of session key in the process of authentication. The analysis shows that the proposed protocol can meet the needs of the wireless sensor network for security authentication, and also has a good performance in authentication time, interaction, computational complexity, and security attacks.
