Secure and Efficient Authenticated Key Exchange Mechanism for Wireless Sensor Networks and Internet of Things Using Bloom Filter

For security sensitive Internet of Things (IoT) and Wireless Sensor Networks(WSNs), an efficient authenticated key exchange (AKE) mechanism improves the quality of services and reduces the possibility of security attacks. In this paper, we propose Bloom filter based authentication scheme suitable for the WSNs and IoT of large hop count (i.e., the large number of intermediate sensor nodes through which data must pass between source sensor node and gateway node). The novelty of our proposed protocol is, it eliminates unauthorized querying message transmission at the initial level (i.e., at the sensor node itself) to avoid bogus message flooding from the sensor nodes to the gateway node (which exhausts the resources of WSNs). We perform the formal and informal security analysis of the proposed schemes using widely accepted AVISPA tool and random oracle model. The computational analysis shows that our system is suitable for resource constrained sensor nodes like TelosB and MicaZ. The relative security and performance analysis results indicate that our scheme is more secure, efficient and robust in comparison to other existing systems.
