Advanced Wireless Metering Infrastructure (AWMI) is becoming an important networking environment for telemetry in power grid control networks. It means that electricity is delivered to many households via power grid networks and advanced digital meter devices read digitally the telemetric data, such as usage of household electricity, and report them over digital control networks, such as wireless mesh networks, to electric utilities for load balancing, accounting, billing, and auditing purposes. One of the major concerns coming from the power grid service utility providers is the integrity of telemetric data sent over these wireless networks. One of the major concerns coming from the service utility users is the privacy of telemetric data over these wireless networks.

In this talk, I will discuss two approaches for handling the privacy of the telemetric data: the Cluster-based Private Data Aggregation (CPDA) that leverages clustering protocol and algebraic properties of polynomials, and the Slice-Mix-AggRegaTe (SMART) scheme based on slicing techniques and the associative property of addition. Both of these schemes are also extendable to preserve integrity of telemetric data aggregation. Simulation results confirm efficacy and efficiency of the presented solutions.

This is joint work with Dr. Wenbo He, Hoang Nguyen, Ying Huang, Xue Liu, and Tarek Abdelzaher.


Klara Nahrstedt is a professor at the University of Illinois at Urbana-Champaign, Computer Science Department. Her research interests are directed towards multimedia middleware systems, QoS-aware resource management in distributed multimedia systems, and security and privacy in mobile peer-to-peer systems. She is the recipient of the Early NSF Career Award, the Junior Xerox Award, the IEEE Communication Society Leonard Abraham Award for Research Achievements, the Ralph and Catherine Fisher Professorship Chair, and the University Scholar Award. She is a Fellow of the IEEE. She was the general chair IEEE Percom 2009, and the elected chair of ACM Special Interest Group in Multimedia (2007-2009).

Nahrstedt received her BA in mathematics from Humboldt University, Berlin, in 1984, and M.Sc. degree in numerical analysis from the same university in 1985. In 1995 she received her PhD from the University of Pennsylvania in the Department of Computer and Information Science.
