In Wireless Sensor Networks (WSNs), data aggregation is defined as the method of acquiring sensed data from neighboring nodes and merged to send data to the base station. It is required to manage the limited in-network processing and storage capacity of nodes in the aggregation process with collaborative computing and also secure communication aspects. In this paper, double cluster head based secure aggregation method (DCSDA) is proposed. The method is more suitable for the cluster based

The experimental evaluation shows the performance of the DCSDA approach in terms of packet drop ratio, delay and energy consumption. The results proved the effectiveness of the DCSCA approach. __________________________________________________________________________________________ the sensor nodes, the algorithm doesn't completely solve the privacy preserving issue. Yoon et al., [26] proposed signature based data aggregation scheme for managing the security at the time of data aggregation in WSNs. The proposed scheme utilized the complex numbers to achieve data integrity and privacy checking in sensor nodes. The authors claimed that the proposed method achieved 50 % more communication over the existing methods. Zhou et al., [27] proposed homomorphic scheme for secure communication (SDA-HP) in WSNs. This scheme applied the symmetric encryption for the homomorphic data and secures the data privacy for WSNs. Proposed Method
