Abstract
In the medical fields, wearable body area sensors network (WBAN) is playing a major role in maintaining user health by providing convenience service for the patient and doctors. However, sensor data transmission in an insecure communication channel enables the attacker from tampering the sensor data, disguising as a legitimate user, or intercepting the forwarded packets from its unprotected sources. A wide variety of secure authentication schemes were proposed to improve the communicated channels’ reliability in protecting the user data. Moreover, those schemes are lacking the guarding of nodes anonymity, key management, and size. Thence, we propose a lightweight WBAN authentication with two protocols P-I for authentication and P-II for re-authentication to protect the nodes anonymity and increase the efficiency. Furthermore, our scheme employed better key management with high randomness of the security parameters to provide higher protection as a trade-off between security and efficiency. The scheme formal proof for the key agreement and mutual authentication is conducted through (Burrows Abadi Nadeem) BAN logic.
