In wireless sensor networks (WSNs) for getting the information about the environment various sensor nodes are distributed in the region. Utilization of minimum energy and secured data transmission are the most challenging issues in WSN. In this work, we are going to use a hierarchical clustering protocol LEACH where for efficiently utilization of energy the remaining energy of each node in every round is considered so that early death of some nodes does not affect network lifetime. This paper also presents a solution for secured data transmission either inside the network or to the base station since. To deal with such kind of threats we have considered different security methods like authentication, encryption, decryption and intruder detection. Analysis and simulation result shows efficiency of proposed protocol in terms of network lifetime, throughput, number of packets to the base station, packet delivery ratio and packet drop ratio.
