Security and Trust in Sensor Networks

Abstract

The concept of security for tiny artifacts has been studied in a widerange of aspects, from authentication through data integrity tointrusion detection. This chapter provides a broad overview of some ofthe techniques developed for constrained devices where computationalpower, memory capacity, and energy limitations enforce slightlydifferent approaches to these problems, when compared to standardhigh-end devices. In the following, we present ideas that leverageunique properties of sensor networks (also wireless sensor networks) toprovide consistent and secure systems for information gathering andsensing.
