Designing a Reconfigurable Security Architecture for Wireless Sensor Networks

Dynamic reconfiguration makes the applications running on a deployed sensor networks dynamically evolve during the lifetime of its deployment. Adaptive security system (ADAPSEC), a reconfigurable security architecture for wireless sensor networks is proposed in this paper to meet the secure needs imposed by dynamic reconfiguration. It encapsulates the security aspects related to protection of communication, resources and component loading and enforces application-specific, fine-grained security policies. Based on ADAPSEC, optimal security policies can be selected and enforced in sensor networks according to the observed external conditions, internal resource constraints and application requirements.
