Never Trust Anyone: Trust-Privacy Trade-offs in Vehicular Ad-Hoc Networks

Abstract

Due to the rapid development of networking and communications technologies, it has made more convenient for consumers to interact with each other to exchange information in Location Based Services (LBSs) and to share digital contents, making privacy and trust protection one of the primary concerns in history of information security. Therefore, in such applications like carpooling, parking no one is trusted (i.e. applications of Vehicular Ad hoc Network (VANET)). In VANET before a genuine communication starts, certain level of trust must be set up among the cooperating substances, which may require that some data that may contain privacy about the entities which is to be shared among the entities. Thus, privacy protection and trust establishment are inter-related issues that ought to be legitimately adjusted to guarantee both a smooth correspondence and for appropriate security insurance or privacy protection. A service request typically reveals the identity (for example, IP address or caller ID) of the user but may incorporate other individual data, for example, area, time, and the kind of the service on demand. This data empowers a Location Service Provider (LSP) to construe after some time a thorough client profile with a high level of accuracy, which thus makes a huge potential for privacy invasions. The exchange of such information can be result of loss of privacy and trust among users and infrastructure. To protect such privacy, several efforts have made in past including Mix Zones. This work discusses maximum facts to improve trust, preserved privacy (with proposing a new design in spite of mix zone which has not been proposed before,), and trade-offs among them, in result this proposal saves time, fuel and cost of vehicle users. Finally, this work concludes that to gain a higher level of trust just, be self–secured i.e. not to disclose everything to someone else, because in this current world, we cannot trust perfectly on anyone.
