Generation of Key Predistribution Scheme Applying Quasi‐Symmetric Designs and Bent Functions in the Wireless Sensor Network
Debashis Ghosh · 2025
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.
