Abstract

Please WBANs are a sensor network for detection and collection of sensitive data to the human body, which is lightweight and mobile. WBANs transmit sensitive and significant messages through the public channel, which makes it easy for an attacker to eavesdrop and modify the messages, thus posing a severe threat to the security of the messages. Therefore, it is essential to put in place authentication and key agreement between different communication nodes in WBANs. In this paper, a lightweight and secure authenticated key agreement protocol in wireless body area networks is designed. It is capable to reduce the cost of sensor node computation while ensuring security. Besides, an informal security analysis is conducted to discuss the security of the protocol against wellknown attacks. Finally, the energy consumption of the protocol is evaluated, and the results show that the sensor nodes only need low storage cost, computational cost and communication cost.
