Abstract
We present the design, implementation and simulation of a security protocol based on Extensible Authentication Proto- col nick-named EAP-Sens for wireless sensor networks. We use the generalized pre-shared key authentication method for authentication and key establishment. Standard EAP model is used for authenticating sensor nodes within the ra- dio range of the authenticator. For distant nodes, we use Relay Authenticators to tunnel EAP messages to the au- thenticator. We have defined EAP message encapsulations for IEEE 802.15.4 standard and a key hierarchy for EAP- Sens. To analyze EAP-Sens performance on larger config- urations a simulation model has been developed. We have implemented an EAP-Sens prototype for Tmote sensors and showed that EAP based security protocol is feasible in wire- less sensor networks.
