Abstract
Localization technology such as GPS is one of the most methods used to guide drivers to their final destination. It is also used in some other applications including tracking. However, it seems that GPS technology by itself might not be sufficient especially in tunnels and mountains. First, to have a strong signal between an orbiting satellite and a GPS receiver, there must be a relatively clear line of sight. Obstructions such as buildings, trees, and large mountain passes can potentially weaken the strength of the signal from the satellites and make the positioning data less reliable. Also, GPS localization signals in most of the tracking applications sent Short Message Service (SMS) that are not never secured. Therefore, SMS signal might be intercepted, eavesdropped, replayed, and modified and this might lead to misguided vehicles, trucks, container cargos and trains. This paper concerns the security of vehicles tracking information for the sake of transportation security. This paper also suggests other localization technology along with GPS for accurate localization such as RFID in addition to proposing a lightweight security algorithm for tracking information.
