AI总结:

本文综述了VANETs中信任模型的分类与比较,指出接收端与发送端信任评估的主要区别,并探讨了未来研究方向及部署挑战。

摘要:

本文综述了车辆自组网络(VANETs)中最新状态的信任模型。信任管理在隔离恶意内部攻击中起着关键作用,而传统安全方法无法有效阻止此类攻击。为此,本文提出了多种信任模型;一些仅涉及信任管理,而另一些则还涉及安全和隐私方面。本文首先回顾、分类并总结了最新状态的信任模型,然后比较了它们的成果。通过这项文献综述,读者可以轻松识别出文献中存在两种主要的信任模型类别,其主要区别在于评估点不同。例如,大多数信任模型遵循接收端信任评估,据我们所知,目前只有单一的VANET信任模型在争议情况下评估信任于发送端。在存在争议时,路侧单元(RSU)裁定事件的有效性。在接收端信任模型中,每个接收方在消息到达时计算发送方及其消息的信任度时会变得忙碌。相反,在发送端类别中,接收方无需进行任何计算,因为信任在消息发布时被验证。此外,车辆可以快速采取行动,例如绕行至替代路线,以支持快速决策。我们通过顺序图比较了这两种评估技术。最后,本文通过建议未来工作来总结信任在VANETs中的发送端评估。此外,在考虑信任模型在VANETs中的部署时,强调了挑战(实时约束和效率)。

英文摘要:

This paper presents a survey of state-of-the-art trust models for Vehicular Ad Hoc Networks (VANETs). Trust management plays an essential role in isolating malicious insider attacks in VANETs which traditional security approaches fail to thwart. To this end, many trust models are presented; some of them only address trust management, while others address security and privacy aspects besides trust management. This paper first reviews, classifies, and summarizes state-of-the-art trust models, and then compares their achievements. From this literature survey, our reader will easily identify two broad classes of trust models that exist in literature, differing primarily in their evaluation point. For example, most trust models follow receiver-side trust evaluation and to the best of our knowledge, there is only one trust model for VANETs which evaluates trust at the sender-side unless a dispute arises. In the presence of a dispute, a Roadside Unit (RSU) rules on the validity of an event. In receiver-side trust models, each receiver becomes busy while computing the trust of a sender and its messages upon the messages' arrival. Conversely, in the sender-side class, receivers are free from any kind of computation as the trust is verified at the time the message is announced. Also, vehicles can quickly act on the information, such as taking a detour to an alternate route, as it supports fast decision-making. We provide a comparison between these two evaluation techniques using a sequence diagram. We then conclude the survey by suggesting future work for sender-side evaluation of trust in VANETs. Additionally, the challenges (real-time constraints and efficiency) are emphasized whilst considering the deployment of a trust model in VANETs
