Simplifying Secure Communications in <scp>WBANs</scp> : Advanced Lightweight Authentication Solutions

ABSTRACT Wireless body area sensor networks, or WBANs, are a modern medical innovation that is helping to keep people healthy by offering doctors and patients a convenient service. The primary source of concern is the transfer of sensor data over an insecure communication route. Attackers may use this vulnerability to capture packets from unsecured sources, tamper with sensor data, or pose as authorized users. Adversaries can easily intercept patient‐medical server data exchange messages due to WBAN's mobility and openness. It allows them to carry out hostile actions such as data manipulation, delay, impersonation, and interruption, which can disrupt real‐time medical data transfer. Because the current WBAN authentication methods developed utilize pricey PKI and cryptographic techniques, they need significant computer power. Since wireless sensors have fixed processing power, they can carry out various tasks for data exchanges, necessitating the creation of an affordable protocol. Therefore, the authentication procedure must be carried out as soon as possible to guarantee the timely delivery of vital medical data. We suggest a dependable mutual authentication technique for WBAN that enables fast data transfer through the hub, intermediate, and sensor nodes. The protocol achieves good security and is well‐suited for WBAN, according to the suggested protocol performance analysis in BAN and Scyther.
