Abstract: How to protect data privacy and data integrity is the major challenge in data aggregation of Wireless Sensor Networks (WSN). This paper proposed an integrity-Energy-Saving Privacy-preserving Aggregation (iESPART), which was based on Energy-Saving Privacy-preserving Aggregation (ESPART). By using a homomorphic message authentication code scheme, iESPART was not only able to protect data integrity, but also able to determine which nodes had been attacked. The simulation results show that iESPART achieves the same data privacy-preserving effect as integrity-protecting Private Data Aggregation (iPDA), with a more comprehensive integrity detection mechanism and less communication overhead.
