As a crucial component of intelligent transportation system, Internet of Vehicles (IoV) plays an important role in the smart and intelligent cities. However, current Internet architectures cannot guarantee efficient data delivery and adequate data security for IoV. Therefore, Named Data Networking (NDN), a leading architecture of Information-Centric Networking (ICN), is introduced into IoV. Although problems about data distribution can be resolved effectively, the combination of NDN and IoV causes some new security issues. In this paper, we apply Communicating Sequential Processes (CSP) to formalize NDN-based IoV. We mainly focus on its data access mechanism and model this mechanism in detail. By feeding the formalized model into the model checker Process Analysis Toolkit (PAT), we verify four vital properties, namely, deadlock freedom, data reliability, PIT deletion faking, and CS caching pollution. According to verification results, the model cannot ensure the security of data with the appearance of intruders. To solve these problems, we construct a blockchain-based mechanism by creating a blockchain-based distribution trusted platform on top of NDN-based IoV. Through the analysis of the improved model, the blockchain-based mechanism can truly guarantee the security of NDN-based IoV.

使用 CSP 对基于 NDN 的 IoV 进行建模和验证

作为智能交通系统的重要组成部分,车联网(IoV)在智慧城市和智慧城市中发挥着重要作用。然而,当前的互联网架构无法保证车联网的高效数据传输和足够的数据安全性。因此,将信息中心网络(ICN)的领先架构命名数据网络(NDN)引入车联网。虽然数据分布的问题可以得到有效解决,但 NDN 和 IoV 的结合带来了一些新的安全问题。在本文中,我们应用通信顺序过程 (CSP) 来形式化基于 NDN 的 IoV。我们主要关注它的数据访问机制,并对该机制进行详细建模。通过将形式化模型输入模型检查器 Process Analysis Toolkit (PAT),我们验证了四个重要属性,即死锁自由度、数据可靠性、PIT 删除伪造和 CS 缓存污染。根据验证结果,该模型无法保证出现入侵者的数据的安全性。为了解决这些问题,我们通过在基于 NDN 的 IoV 之上创建基于区块链的分布式可信平台来构建基于区块链的机制。通过对改进模型的分析,基于区块链的机制能够真正保证基于NDN的车联网安全。
