【摘要】：车联网是车辆与车辆之间以及车辆与基础设施之间,通过无线通信形成的网络。由于无线网络的开放性,车联网易于受到各种攻击,面临各种安全威胁。本文研究的是车联网安全通信中的隐私保护问题,涉及身份隐私、位置隐私和数据隐私问题,主要开展了如下两个方面的工作:首先,本文设计了一个公务用车通信协议。公务用车是指用于履行公务的机动车辆,一般采用集中管理,公务人员用车时可临时分配。公务用车既需要受到一定的监督,同时又有一定程度的保密需要,以保障公务活动的展开。本文设计的协议结合了同态密钥协商、对称式加密、信息验证和数字签名等机制,确保了公务用车的通信安全和隐私保护。其次,本文提出了一个长途客车多媒体点播通信协议。在长途客车上进行多媒体点播时,乘客既要得到服务,也要求其身份、位置、数据等隐私受到保护。本文提出的协议结合了基于身份验证的假名、公平盲签名理论和数字签名等机制;性能分析表明,该协议能够满足车联网安全通信需求,保护乘客隐私,并提高通信效率。
[Abstract]:Vehicle networking is a network formed by wireless communication between vehicle and vehicle and between vehicle and infrastructure. Because of the openness of wireless network, vehicle networking is vulnerable to various attacks. Facing all kinds of security threats, this paper studies the privacy protection problem in the security communication of vehicle network, which involves identity privacy, location privacy and data privacy. The main work is as follows: first, In this paper, a communication protocol for official vehicles is designed. Official vehicles are motor vehicles used to perform official duties, which are generally centrally managed and can be temporarily distributed when public servants use their vehicles. Official vehicles need to be subject to a certain degree of supervision. At the same time, the protocol designed in this paper combines homomorphic key agreement, symmetric encryption, information verification and digital signature. The communication security and privacy protection of official vehicles are ensured. Secondly, this paper proposes a multimedia on-demand communication protocol for long-distance buses. When carrying out multimedia on-demand broadcasting on long-distance buses, passengers not only need service, but also require their identity and location. Data and other privacy are protected. The proposed protocol combines pseudonym based on authentication, fair blind signature theory and digital signature mechanism, and performance analysis shows that the protocol can meet the needs of secure communication and protect the privacy of passengers. And improve the communication efficiency.
