A lightweight and secure multilayer authentication scheme for wireless body area networks in healthcare system

Abstract

<span lang="EN-US">Wireless body area networks (WBANs) have lately been combined with different healthcare equipment to monitor patients' health status and communicate information with their healthcare practitioners. Since healthcare data often contain personal and sensitive information, it is important that healthcare systems have a secure way for users to log in and access resources and services. The lack of security and presence of anonymous communication in WBANs can cause their operational failure. There are other systems in this area, but they are vulnerable to offline identity guessing attacks, impersonation attacks in sensor nodes, and spoofing attacks in hub node. Therefore, this study provides a secure approach that overcomes these issues while maintaining comparable efficiency in wireless sensor nodes and mobile phones. To conduct the proof of security, the proposed scheme uses the Scyther tool for formal analysis and the Canetti–Krawczyk (CK) model for informal analysis. Furthermore, the suggested technique outperforms the existing symmetric and asymmetric encryption-based schemes.</span>

Current security and privacy posture in wireless body area networks

“…Insider threats, where authorized users with malicious intent exploit their privileges, are a significant concern in WBANs. Research is required to develop techniques that can detect and mitigate insider threats, such as unauthorized access or data leakage, within WBANs [234]- [239]. This includes anomaly detection, behavior analysis, and secure user management mechanisms to identify and respond to insider threats effectively.…”
