NPKG: Novel Pairwise Key Generation for Resisting Key-based Threats in Wireless Sensor Network

Securing the communication system in Wireless Sensor Network (WSN) is still an open-end problem in spite of series of dedicated research work for more than a decade. This paper presents a Novel Pairwise Key Generation (NPKG) technique intended for resisting replication attacks as well as other forms of attacks that are related to secret keys in WSN. The proposed system also harness the potential role of a base station and trusted authority which otherwise represents a mock module in existing studies. Designed using an analytical method, the proposed study particularly emphasize on achieving a balance between minimal resource utilization and ultimate security feature of both forward and backward secrecy for further strengthening privacy, confidentiality, and nonrepudiation in WSN. The algorithm is exclusively designed to handle the possible security issues in a dynamic network of WSN for its upcoming applications. The study outcome shows better algorithm performance in contrast to the existing system.
