Abstract

Due to various restrictions in wireless sensor networks (WSN), the unilateral pair-up, and the security of self-configured and infrastructure-free communication among the nodes, key predistribution techniques have lately become a leading research area. Across all other best practices, the implementation of a combinatorial tool provides a premier foundation for key distribution within terminals. The purpose of this study is to design a key distribution technique by utilizing a combinatorial design to effectively address not only the operational performance but also the security needs of the network. In our scheme, we use the attributes of triangle-free quasi-symmetric 2-designs (TFQSD) in key allocation across sensor nodes to minimize the storage capacity. The scheme is represented by a block graph known to be the strongly regular graph connected to TFQSD. The confidentiality of the designed network is investigated by analyzing the parameters of the graph based on Bent Boolean functions.
