EAP-Sens: a security architecture for wireless sensor networks
نویسندگان
چکیده
We present the design, implementation and simulation of a security protocol based on Extensible Authentication Protocol 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 radio range of the authenticator. For distant nodes, we use Relay Authenticators to tunnel EAP messages to the authenticator. We have defined EAP message encapsulations for IEEE 802.15.4 standard and a key hierarchy for EAPSens. To analyze EAP-Sens performance on larger configurations 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 wireless sensor networks.

متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
