Preventing Radio Window Attacks
Abstract
Major Goals: Radio frequency (RF) signals emanating from any wireless network within a protected area (home, commercial, government, or military facility), creates a radio window, even through concrete walls, that can be used to track and infer peoples movements, activities, breathing rates, and even the sounds inside the facility, by attackers with receivers outside of the facility. The major goals and objectives of the overall project were as follows: 1. Develop a novel game theoretic framework where the defender (the genuine wireless network) deploys multiple transmitters in different locations and changes transmitters in a probabilistic manner to minimize the chance of the attack receivers being able to classify the activities of people inside certain parts of the building. The framework will incorporate optimizations related to trade-offs between obfuscation methods and the cost of obfuscation. 2. Develop and examine general multi-antenna MIMO-based defense methods to confuse the attacker. 3. Develop new estimation bounds which quantify an attackers ability to estimate a persons track over time. Such bounds will inform evaluations of the robustness of particular wireless networks to the radio window attack as a function of its transmitters locations, transmit powers, bandwidth, number of antennas, and data rate. 4. Evaluate the attacks and defense mechanisms within our framework through extensive experiments. The goal here is to understand how the developed models apply to real situations and very importantly, how the experimental evaluations validate and further strengthen the framework, models, and defense mechanisms.
