Abstract
Security and privacy bear paramount importance for wireless body area networks (WBAN) that collect and transmit vital signs of patients and provide continuous health monitoring. Security mechanisms successful in conventional networks and systems may not work in WBAN due to hardware constraints, device heterogeneity, system usability, and compatibility. Recent research on security and privacy in WBAN has been focused on lightweight and non-intrusive solutions that utilize resources widely available to most WBANs. This chapter provides an overview of the state-of-the-art technologies in this area. In particular, we emphasize recent techniques for device authentication and secret key extraction. Pros and cons of these techniques are analyzed and compared. Future directions in this area of research are also discussed.
