Security Challenges of Wireless Body Area Networks: Threats and Solution

Abstract

Wireless Body Area Networks (WBANs) are composed of a set of sensors and devices, that collect, store, process, and send physiological information. The collected data can be used to monitor elderly people, the activity of an athlete and many other benefits. However, physiological, and medical information are classified as private data, thus, WBANs applications must implement security models to protect the collected information during collection, transmission, and storage procedures. Indeed, several security requirements must be addressed in WBANs. This paper aims to present the architecture of WBANs, review the security requirements, and discuss the type of attacks and threats that can influence the performance and efficiency of WBANs.
