Several data aggregation schemes based on privacy homomorphism encryption result in a better security compared with traditional aggregation.  In the proposed Recoverable Concealed Data Aggregation scheme, the Cluster Heads can aggregate the sensing data of the individual Sensor Node present in the cluster without decryption which reduces the transmission over head. The Concealed Data Aggregation is extended with symmetric key encryption. The base station can retrieve or recover the application specific data from the aggregated cipher text. The contribution of this scheme is that it mitigates the impact of compromising attacks.
