ABSTRACT
It has been widely accepted that body sensor networks (BSN) will take an important role in mobile telemedicine systems as the basic interface for biological data collection, fusion, and drug delivery. To protect the vital medical information, effi - cient security mechanisms must be properly deployed in a resource-constrained wireless BSN, which faces more serious security challenges compared with a wired BSN, e.g., one that uses e-textile materials to connect the various sensors. Th is chapter introduces a variety of security techniques that are applicable to wireless BSNs, with emphasis on a novel biometrics method that utilizes the biological channels (bio-channels) to assist secure information transmission.
