LIMAP: A Lightweight Multilayer Authentication Protocol for WBAN

Wireless Body Area Networks (WBANs) are emerging technologies used in the medicinal market for various applications. They connect sensors throughout the human body and hence possibly used to monitor health. However, one of the significant disadvantages of WBANs is notable security and protection problems that need rectification to protect critical data. In previous researches, WBANs have single-layer authentication protocols that are not compatible with their device design qualities, and malicious attackers can take advantage of this. For this purpose, this work has introduced a lightweight and multilayer authentication protocol for WBANs, which uses one-to-one group authentication and group key development algorithm with low software costs to communicate between personal digital assistants and sensor hubs. This model presents the Elliptical Curve Algorithm using Foci calculation, which provides low computing cost, high security, etc., that further integrates with the hash function. Finally, the security and implementation analysis reveal the stability and effectiveness of our convention. All key generations and validations used in our protocol implemented are for better performance and efficiency.
