A design proposal of security architecture for medical body sensor networks

The existing standards of wireless personal area networks (WPANs) in terms of security specifications are not fully applicable to body sensor networks (BSNs) because of some inherent security vulnerabilities and stringent resource constraints. This study outlines a new design proposal of security architecture for BSNs with the purpose of high-level security as well as light-weight protocol. The novelty of this proposal includes: i) the use of bio-channel to assist secure transmission of privacy data, which is unavailable in other kinds of wireless networks; and ii) the multi-purpose use of physiological data for various security aspects
