Wireless Body Area Network Identity Authentication Protocol Based on Physical Unclonable Function

摘要

Aiming at the malicious attacks caused from the sensor identity authentication in wireless body area networks (WBAN), the sensor cannot transmit information normally and even cause the life-threatening problem. In this paper, the physical unclonable function module is added to the sensor of the wireless body area networks, and an energy-saving, real-time sensor authentication protocol is proposed. The energy consumption of the authentication protocol based on the physical unclonable function is studied by analyzing the energy consumption of the authentication based on the public key cryptosystem and the physical unclonable function of the IOT device. The simulation results show that the authentication protocol can reduce the energy consumption of authentication when the networks security is satisfied.
