Abstract. This paper addresses the trust management problem in the emerging Vehicular Social Network (VSN). VSN is an evolutionary integration of Vehicular Ad hoc NETwork (VANET) and Online Social Networks (OSN). The application domain of VSN inherits the features of its parental VANET and OSN, providing value-added services and applications to its consumers, i.e. passengers and drivers. However, the immature infrastructure of VSN is vulnerable to security and privacy threats while information sharing, and hard to realize in the mass of vehicles. Therefore, in this paper, we particularly advocate for communication trust establishment and management during information exchange in VSN. First, we establish functional architectural frameworks for VSN that are based on the underlying applications. Second, based on these frameworks, we propose two trust establishment and management solutions, i.e. email-based social trust and social networks-based trust, to target different sets of applications. Third, we discuss the contemporary research challenges in VSN. Our proposed scheme is a stepping stone towards the secure and trustworthy realization of this technology.

Introduction
Vehicular Ad hoc NETwork (VANET) is poised to offer the drivers and passengers with a safe, at least fail safe, reliable, and infotainment-rich driving environment. From the research results in the field of vehicular networks (semiautonomous) and driverless (autonomous) cars, it can be easily speculated that intelligent transportation system (ITS) technologies, which are realized through VANET, will be soon pervading our highways. There are few challenging issues c Springer International Publishing Switzerland 2016 H.T. Nguyen and V. Snasel (Eds.): CSoNet 2016, LNCS 9795, pp. 214–225, 2016. DOI: 10.1007/978-3-319-42345-6 19

that are keeping the stakeholders and investors at bay from deploying these technologies on a mass scale. These issues include security, privacy, trust, framework design, initial deployment, data and user privacy, to name a few [17]. The mobility patterns, based on space and time, are predictable in VANET and linked to online social networks (OSNs). For example, the traffic tends to be dense during rush hours because people are going to office in the morning and coming back home in the evening, which is not the case for non-peak hours. This phenomena develops a unique social relationships among neighbors who tend to share same interests and/or likely schedule. The recent developments in OSNs gives rise to the concept of VSN [19] by providing a preferred mean of sharing social
