With the rapid development of network communication technology,the internet begins to carry more and more application services,it brings forward very high demands for network data aggregation.So,designing a data aggregation scheme which can protect both data privacy and integrity seems very important.It presents a complex field-based new WSN data aggregation algorithm for integrity protecting.It adds privacy seed to the real sampling data in order to preserve privacy and protect data integrity by using the associated characteristics between the real part and imaginary part of complex numbers.Moreover,depending on its own characteristics of data aggregation tree structure,the algorithm decreases data communication overhead and computation overhead.Theoretical analysis shows that,in all attacking cases,the algorithm achieves good integrity protection performance.The simulation results show that under the premise of privacy preserving and integrity protecting,the algorithm can get accurate data aggregation result,just spending the same time of TAG.
