Efficient distributed security for wireless medical sensor networks
Oscar García Morchon, Heribert Baldus · 2008
Wireless medical sensor networks (MSNs) enable ubiquitous health monitoring of users during their everyday life, at home or at hospital, without restricting their freedom. MSNs improve therefore users’ wellbeing and help to quickly react during emergency situations. Security is a key requirement to guarantee safety and privacy of MSN users. However, the resource-constrained nature of the sensor nodes and the operational requirements of these networks hinder the use of traditional security methods.
