Abstract: In order to solve the security problems existing in wireless sensor networks, such as privacy exposure, information tampering and false data injection, an energy-saving privacy protection integration scheme ESIPPA is proposed, which supports integrity verification. The ESIPPA scheme can detect unauthorized tampering of information on the basis of data privacy protection and ID privacy protection. It sends recessive ID number by the way of weighting, and makes ID number as a factor of interference formula which is used to implement interference for data, to improve the security of privacy protection. By constructing a model of double integration trees and making full use of base station with high energy, the ESIPPA can reduce the burden of nodes and validate data integrity. The simulation results show that the ESIPPA scheme respectively reduces 7. 5% and 15. 4% in the aspect of communication traffic compared with that of integration-preservation data aggregation scheme based on distributed authentication and DCSA scheme and it also better protects the integrity and privacy of data.
