Wireless Sensor Networks (WSNs) face security threats while sending and receiving data. The data transmission must be secured with reduced energy consumption. To enhance the security of sensor nodes, the data transmitted must be encrypted among sensor nodes. In this paper, the authors applied data encryption standard scheme to add security to LEACH protocol. This paper is to add secret encryption scheme to the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol. The network model is simulated in Matlab to obtain the results.
