Abstract: The upcoming Smart Grid is envisioned to use communication networks for two-way flow of data that will be generated from several new applications. These applications will run on different components of Smart Grid communication network includ-ing Neighborhood Area Networks, Home Area Network and Wide Area Networks. For each of these network components, various underlying infrastructure alternatives and standards based on wireless, fiber, powerlines, etc. are being considered for development. In this presentation, I will first talk about the wireless networking infrastructure options for the implementation of Neighborhood Area Networks. Particularly, I will look at the possibility of applying IEEE 802.11s and Zigbee mesh standards. In the second part of the presentation, I will look at privacy concerns due to smart meter data collected through the Neighborhood Area Networks. The collection of near real-time household energy consumption may reveal a lot of information about the life and behavior within the home. Therefore, in addition to traditional security problems, researchers need to tackle the pri-vacy issues raised as a result of the implementation of the Smart Grid Advanced Meter-ing Infrastructure (AMI). I will describe two approaches to provide consumer privacy on AMI: The first approach relies on generating obfuscation values to hide the actual usage from eavesdroppers and utility companies while preserving the utility companies’ ability to use the data for state estimation. The second ap-proach is the ultimate solution that relies on fully homomorphic encryption systems. I will talk about the feasibility of using these two approaches on an IEEE 802.11s-based AMI network.
