Trust on the Ratee: A Trust Management System for Social Internet of Vehicles

Abstract

The integration of social networking concepts with Internet of Vehicles (IoV) has led to the novel paradigm "Social Internet of Vehicles (SIoV)," which enables vehicles to establish social relationships autonomously to improve traffic conditions and service discovery. There is a growing requirement for effective trust management in the SIoV, considering the critical consequences of acting on misleading information spread by malicious nodes. However, most existing trust models are rater-based, where the reputation information of each node is stored in other nodes it has interacted with. This is not suitable for vehicular environment due to the ephemeral nature of the network. To fill this gap, we propose a Ratee-based Trust Management (RTM) system, where each node stores its own reputation information rated by others during past transactions, and a credible CA server is introduced to ensure the integrality and the undeniability of the trust information. RTM is built based on the concept of SIoV, so that the relationships established between nodes can be used to increase the accuracy of the trustworthiness. Experimental results demonstrate that our scheme achieves faster information propagation and higher transaction success rate than the rater-based method, and the time cost when calculating trustworthiness can meet the demand of vehicular networks.

Trust management in social Internet of vehicles: Factors, challenges, blockchain, and fog solutions

“…The social relationships and past social interactions between vehicles, their drivers, passengers and infrastructure impact the trust between vehicles. 24 A vehicle will trust other vehicle more if they had past collaboration to satisfy some application requirements. The past successful social interaction builds strong relationships between objects.…”

“…This section highlights the most suitable trust models that have a decent realization for SIoV networks.

The trust factors are categorized further in reliability, quality of service (QoS), robustness, and social trust.…”

TACASHI: Trust-Aware Communication Architecture for Social Internet of Vehicles

“…Unlike existing trust models, Gai et al [18] proposed a trust management system for SIoV called RTM where each node stores its own reputation information rated by others during past transactions. They introduced a CA server to ensure the integrity and the undeniability of the trust information.…”

“…In the following, we will compare the obtained dishonesty detection ratios to ones of RTM [18] and AD-IoV [28]. Afterward, we will analyze the generated error ratios with and without the use of our proposed OSN-aided trust architecture.…”

Trust enforcement in vehicular networks: challenges and opportunities

“…VSNs can be employed in fully decentralised VANETs, centralised cloud‐based vehicular networks and controlled edge‐based networks [75]. A related taxonomy can be found in [76], and recent proposals can be found in [77, 78].…”
