In many situations, false location information may impact the security or objectives of the system to which it has been supplied. Research concerning localization and location verication addresses this issue. The majority of solutions, however, revolve around a trusted infrastructure to provide a certied location. This thesis presents an enhanced design for a location verication system, moving verication away from infrastructure-based approaches. Instead, an ad hoc approach is presented, employing regular local devices in the role usually reserved for trusted entities - the role of the evidence provider. We begin with an introduction to the area of localization, outlining the primary techniques employed. We summarize previous approaches, highlighting the improvements and outstanding issues of each. Following this, we outline a novel metric for use with distance bounding to increase the accuracy of evidence extracted from the distance bounding process. We show through emulation that this metric is feasible within an IEEE 802.11 wireless network. We detail the Secure Location Verication Proof Gathering Protocol (SLVPGP), a protocol designed to protect the process of evidence gathering. We employ our novel metric to conrm the presence of a device in an area. We repeatedly extend the SLVPGP's basic design to form three protocols, each with increasingly stronger security.
