Secret Dynamic Key Authentication and Decision Trust Secure Routing Framework for Internet of Things Based WSN

Internet of Things (IoT) devices has risen drastically due to the advancement of Information and communication technologies. Wireless sensor network (WSN) performs a key function in the development of IoT applications like smart factories, transportation systems, military, smart cities, healthcare systems, etc. However, energy, memory, processing and computation resources are the restrictions included in such smart devices. Along with these restrictions, achieving reliability with secure data transmission is a fundamental challenge for WSN. To overcome these challenges, a dynamic key authentication and energy efficient secure routing protocol is proposed in this paper. The proposed approach consists of node clustering, cluster head (CH) selection, key authentication and secure routing. In WSN, sensor nodes (SNs) are deployed randomly. Energy efficient seagull K-medoid clustering (SKC) algorithm is proposed to cluster these SNs based on the intrinsic qualities of nodes and CH is selected using Rider Bald Eagle Search (RBES) algorithm. Next, the Key agreement process is carried out using a Dynamic key authentication scheme, which offers safer data transmission over the network as security is an important factor. Finally, Decision trust routing protocol is introduced for the secure and effective routing for IoT based WSN. MATLAB is the implementation tool used for experiment. The experimental results showed the proposed method is efficient for energy efficient and secure routing than the existing methods.
