Achieving Privacy and Integrity of Data Aggregation in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) were originally motivated by military applications, and are becoming integral part of more and more civilian applications to improve quality of life. With current wireless sensor network technology, people will gain advanced knowledge of physical and social systems, and the advent of a ubiquitous sensing era is coming. In-network processing or data aggregation is an essential function of WSNs to collect raw sensory data and get aggregated statistics about the measured environment, and help queriers capture the major feature or changes of the measured systems. As more and more applications of WSNs collect sensitive measurements of people's everyday life, privacy and security concerns draw more and more attention.
