TrustWalker: An Efficient Trust Assessment in Vehicular Internet of Things (VIoT) with Security Consideration

Abstract

The Internet of Things (IoT) is a world of connected networks and modern technology devices, among them vehicular networks considered more challenging due to high speed and network dynamics. Future trends in IoT allow these inter networks to share information. Also, the previous security solutions to vehicular IoT (VIoT) much emphasize on privacy protection and security related issues using public keys infrastructure. However, the primary concern about efficient trust assessment, authorized users malfunctioning, and secure information dissemination in vehicular wireless networks have not been explored. To cope with these challenges, we propose a trust enhanced on-demand routing (TER) scheme, which adopts TrustWalker (TW) algorithm for efficient trust assessment and route search technique in VIoT. TER comprised of novel three-valued subjective logic (3VSL), TW algorithm, and ad hoc on-demand distance vector (AODV) routing protocol. The simulated results validate the accuracy of the proposed scheme in term of throughput, packet drop ratio (PDR), and end to end (E2E) delay. In the simulation, the execution time of the TW algorithm is analyzed and compared with another route search algorithm, i.e., Assess-Trust (AT), by considering real-world online datasets such as Pretty Good Privacy and Advogato. The accuracy and efficiency of the TW algorithm, even with a large number of vehicle users, are also demonstrated through simulations.

IoT Security Review: A Case Study of IIoT, IoV, and Smart Home

“…[37,38] As IoT is decentralized, assessing its trustworthiness is very challenging. Therefore, minimizing the ambiguity of the service mode of IoV systems, clarifying the intention of information use, legally binding suppliers, and adopting the concept of privacy by design can improve the privacy security of users and promote establishment of the trust in IoV [39].…”

Security in Vehicular Ad Hoc Networks: Challenges and Countermeasures

“…Previous security solutions to vehicular Internet of ings (VIoT) focus more on privacy protection and security-related challenges using PKI. Sohail et al [91] proposed a new scheme, trust enhanced on-demand routing (TER). is scheme overcomes the security challenges in VIoT, such as efficient trust assessment, certified user nonfunctioning, and secure information diffusion.…”

Current Research Trends in IoT Security: A Systematic Mapping Study

“…Topic 5 is related to risk assessment and prioritization of IoT security threats. For a secure IoT environment, various Mobile Information Systems studies have prioritized security threats by applying approaches such as product-development life cycle, decisionmaking trial-and-evaluation laboratory, analytic network processing, and graph theory to develop risk assessment and management frameworks [200][201][202][203][204][205][206][207].…”
