An Improved Privacy Solution for the Smart Grid

Recent advances in hardware, software, computing, and communication technologies have enabled the design and deployment of a smarter, interactive, dynamic 21st century electrical grid, also known as the smart grid. The bi-directional flow of information between the customer premise and the utility provider opens up several privacy challenges that must be addressed. We describe possible man-in-the-middle attacks against one (proposed by Marmol et al.) of the recently proposed privacy solutions for the smart grid environment. To address this vulnerability, we propose an improved privacy solution. We demonstrate the robustness and efficiency of our solution through a detailed security analysis.
