Abstract: A secure privacy-preserving data aggregation (SPPDA) scheme was proposed to preserve data privacy and integrity during data aggregation in wireless sensor network. Firstly, a complex number is composed from the private factor of the nodes and the original data; then the complex number is encrypted with homomorphic encryption method,which can realize the data aggregation in the case of not decrypt ciphertext. Also,the reliability of date is ensued by using integrity verification method based on complex.Theoretical analysis and simulation results show that computational cost and communication overhead of the SPPDA are less, and accuracy of data aggregation results is high.
