A Secure Authentication Scheme based on Brownian Motion in hierarchy Wireless Sensor Networks

In the last few years, the Internet of Things (IoT) has experienced exponential advancements. In IoT infrastructures, Wireless Sensor Network (WSN) has been considered as one of the crucial technologies to support a lot of amazing services. To fulfill new requirements of deployed network environments, the security issue in wireless sensor networks has to be met new challenges such as secured and lightweight requirements simultaneously. Hence, in this paper, an authentication scheme based on the watermarking technique is proposed to secure the sensory data in hierarchy wireless sensor networks. Especially, natural movement characteristics of a sensor node are exploited to provide a conveniently watermarked data, that can be used to validate and detect data integrity attacks in familiar methods. The proposed authentication scheme is evaluated by numerical results and theoretically analyzed to prove a proposal efficiency.
