Secure Data Aggregation in Wireless Sensor Networks

Vimal Kumar, Sanjay Madria

Abstract: The inherent resource constraints associated with wireless sensors make it important to minimize data transmissions within the network so that the sensor lifetime is improved and the network works for a longer period of time. Data aggregation is one such technique where data originating at different sensors is combined and transmitted together. This in-network processing of data helps in reducing the wireless communication but it also makes the task of providing security to the data much more challenging. In this chapter, we motivate, review and discuss research issues in secure data aggregation. In particular, we provide a discussion on general secure data aggregation framework and survey a few existing secure data aggregation schemes.
