In the existing secure data aggregation techniques, reduction in the energy consumption is not much discussed and combined solution for both integrity and authentication is not addressed. In this paper, the authors propose to design an Energy Efficient Secure Data Aggregation Protocol for wireless sensor networks. In this protocol, they incorporate the authentication and security to maintain the efficiency of the data aggregation. First the network is divided into clusters, each cluster is headed by an aggregator and the aggregators are connected to sink either directly or through other aggregators.
