Secure and privacy-enhancing LBS

Abstract: The rapid growth of population and the increasing number of vehicles haveled to high accident rates and cause frequently traffic congestion, especiallyin densely populated countries. There is an urgent need to develop and deployIntelligent Transport Systems (ITSs), in order to improve traffic efficiencyand reduce traffic accidents. The emergence and development of advancedtechnologies lays a good foundation for ITSs; for example, wireless communicationand sensing technologies. To promote the popularity of ITSs, we proposesmartphone-based ITSs, in which a smartphone is a part of the ITSs and actsas an interactive interface for users. We choose the widely used and openAndroid operating system as our platform and we demonstrate how to developvehicular applications in Android by making use of Android Interface DefinitionLanguage (AIDL). Security is a critical requirement in development of allkinds of distributed systems, and it should be taken into consideration in thedevelopment of ITSs as well. We studied several security schemes designed forITSs and improved them to better fit the limited computation capabilities andpower of smartphones. The security modules and the client applications areseparated, which makes the applications easier to maintain and use. The projectcarried out evaluation for the implemented security schemes. Our evaluationresults show the practicality of our implementation, which means the securityschemes fit the limited resource of smartphone.
