Securing Mobile Location-Based Services Through Position Verification Leveraging Key Distribution

Technological advancements have made it possible to use information associated with a mobile's location to form new computing and services. One concern with these emerging Location-Based Services (LBS) is their ability to provide security while remaining reliable and accurate. In this paper, the authors focus on securing Mobile Location-Based Services (MLBS), where certain goods or services are provided by mobile vendors to a clientele based on the proximity of vendors to potential customers. They identify different attacks and misuse faced by MLBS, and show that position verification is a critical step in providing a secure and trustworthy MLBS.
