The privacy preserving data aggregation protocols in wireless sensor networks have many applications in security critical areas, since it hides individual nodes' data from adversaries. The existing hop by hop and shuffling based privacy preserving protocols does not provide an energy efficient, accurate and secure data aggregation result in base station, due to the energy consuming decryption at the aggregator node, reveals large amount of privacy protected information to adversaries, thereby it loses end to end confidentiality of data and allows the adversary to generate inaccurate results.
