A location enabled wireless security system

We describe a method for merging the concepts of GPS positioning and intrinsic wireless network positioning into a high-level wireless security system. Specifically, we outline how the wireless network can assign a quantitative security level associated with the probability that a wireless network node is in a false location. We demonstrate the operational limits of the system using unbiased Cramer-Rao bounds in an ad hoc network. We also outline several additions that can be added to the security system, when position locations are influenced by other factors. This new location-based method allows for a tamper-proof security technique designed to complement existing encryption technologies.
