Rotation-based privacy-preserving data aggregation in wireless sensor networks

Wireless Sensor Network is an important part of the Internet of Things. Data privacy preservation in wireless sensor networks is extremely urgent and challenging. To address this problem, we propose in this paper a privacy-preserving data aggregation protocol in wireless sensor networks. Compared to the previous research, our protocol protects the actual data from other nodes based on a rotation scheme while reducing communication overhead dramatically. The protocol achieves accurate aggregation results. Finally, theoretical analysis and simulation results confirm the high privacy and efficiency of our proposal.
