Abstract

A LOCATION ENABLED mobile devices proliferate, location-based services is rapidly becoming immensely popular. Most of the current location-based services for mobile devices such as on user’s current location. Users discover their locations and share them with a server. In turn the server performs computation based on the location information and returns data/services to the users. Our distance bounding scheme is designed for ad-hoc mobile users generating location proofs for each other in a distributed setting. However, it can easily accommodate trusted mobile users and wireless access points. Our distance bounding scheme ensures the integrity and non -transferability of the location proofs and protects user’s privacy. Our prototype implementation on the Android stage shows that our distance bounding scheme is Low cost in terms of computational and storage possessions.
