For wireless sensor networks, data aggregation scheme minimize a large amount of transmission data to the base station, so that improve the energy efficiency and prolong the wireless network lifetime. CDA provides end-to-end security i.e. even though the sensed data are encrypted on the sensor nodes and not decrypted before the sink node in this paper, all the homomorphic encryption techniques and various attacks is categorized, but CDA schemes are not satisfy multi-application environments and not provide secure counting; so they may suffer unauthorized aggregation attacks, therefore, a new concealed data aggregation scheme based on homomorphic public encryption system.
