As location-based applications become ubiquitous in emerging wireless networks, Location Verification Systems (LVS) are of growing importance. In this paper, the authors propose, for the first time, a rigorous information-theoretic framework for an LVS. The theoretical framework they develop illustrates how the threshold used in the detection of a spoofed location can be optimized in terms of the mutual information between the input and output data of the LVS. In order to verify the legitimacy of their analytical framework they have carried out detailed numerical simulations. Their simulations mimic the practical scenario where a system deployed using their framework must make a binary Yes/No "Malicious decision" to each snapshot of the signal strength values obtained by base stations.
