In recent years, many researchers have focused on wireless sensor networks and their applications. Toobtain scalability potential in these networks most of the nodes are categorized as distinct groups namedcluster and the node which is selected as cluster head or Aggregation Node offers the operation of datacollection from other cluster nodes and aggregation and sending it to the rest of the network. Clusteringand data aggregation increase network scalability and cause that limited resources of the network are usedwell. However, these mechanisms also make several breaches in the network, for example in clusterednetworks cluster head nodes areconsidered Desirable and attractive targets for attackers since reachingtheir information whether by physical attack and node capturing or by other attacks, the attacker canobtain the whole information of corresponding cluster. In this study secure clustering of the nodes areconsidered with the approach of reducing energy consumption of nodes and a protocol is presented that inaddition to satisfying Advanced security needs of wireless sensor networks reduces the amount of energyconsumption by the nodes. Due to network clustering there is scalability potential in such a network andAccording to frequent change of cluster head nodes load distribution is performed in the cluster andeventually increase the network lifetime.
