An efficient secure key establishment method in cluster-based sensor network

The main issue for the security of wireless sensor networks (WSNs) is how to allow nodes (SNs) establish and share cryptographic keys in an energy-efficient, storage-efficient, authentic manner their secure data transmission. Furthermost recent studies carried out this direction concerned with homogeneous which all has identical characteristics fundamental administration mechanisms. However, Cluster-based have demonstrated better achievements performance than because several benefits clustering. This inspired us propose a key-establishment method cluster-based based on symmetric-key cryptography. Since symmetric key cryptography small energy consumption, they are great choice prefer securing networks. Even though high storage needs, deficiency can be reduced by using suitable methods—evaluating proposed work that needs along consumption. offers favorable level against various intruders possible threats additionally scalable state-of-the-art techniques.
