A Security Framework for SenSearch

We have described the design and a preliminary prototype implementation of a security and privacy framework for SenSearch, which is a search and rescue system for locating people in emergency situation in wilderness areas. Security and privacy is extremely important in such systems, because they collect location and movement information about a person. Our framework carefully employs both symmetric and asymmetric key cryptography. Preliminary performance measurements show that our framework is feasible and provides the required support for security and privacy.
