Abstract: Secure communication of Data in cognitive radio networks is one of the challenging tasks to increase the lifetime of the network is a major constraint. The life time of the network is determined by the energy consumed by the each node and protect the data from an intrudes. In this research work we introduce a secure cluster based communication to reduce the overheads and provide the security. A special node called as centralized node collects the data from clusters and forwards them to Base station. The data is secured which authenticates the Cluster head using the shared secret key and the Digital Signature. The simulation results prove that our algorithm is more efficiently secure the data and achieves more energy savings.
