Research of Privacy Preservation of Data Aggregation in Wireless Sensor Networks

Abstract

In wireless sensor networks, the private data collected by nodes are often aggregated to the base station for some important judgments and operations. How to ensure the privacy of the data aggregation process in wireless sensor networks has become a very important topic. This paper first combs various attacks on data privacy in wireless sensor networks, then combs and evaluates the common privacy preservation technologies, and finally prospects the future research work.
