[Legacy Report] Secure Data Access in Unattended Sensor Networks

Sensor networks are large-scale multi-hop wireless networks consisting of densely deployed, spatially distributed, and autonomous devices using sensors to cooperatively monitor biological, physical, or environmental phenomena. Many sensor networks are envisioned to be deployed in remote and extreme areas such as oceans, mountains, and deserts, where there is no "always-on" high-speed communication link connecting the sensor network to the outside
data center. The sheer amount of data continuously generated, therefore, must be stored inside the network and accessed on demand. Security and privacy issues are the key factors that determine the proper functioning of an unattended sensor network. This talk will address the latest solutions to two issues which have not received enough attention. The first will discuss how to realize distributed privacy-preserving access control in sensor networks such that only authorized users can access the sensed data, while no one, including the network owner, can tell the identity of any user. The second will illustrate how a data user (e.g., the sink) can verify the authenticity and correctness of any query results by taking multidimensional range queries as an example.
