The Internet of Vehicles (IoVs) is one of the most popular techniques among the applications of Internet of Things. The existing IoVs are mainly protected by public key cryptographic systems, which provide identity authentication and information security. Nevertheless, using the proposed Shor's algorithm, the security of all classical cryptographic schemes will be exposed to future quantum computer technologies. Fortunately, based on the unconditional security property of quantum mechanics, direct communication protocols can resist quantum computer attacks and deliver secret messages directly without the requirement of pre-shared keys. For IoV networks, we present a continuous-variable quantum secure direct communication (CV-QSDC) protocol in which the orbital angular momentum (OAM) is used as the information carrier. For one thing, the field of continuous-variable quantum communication system is compatible with the standard telecommunication technology; for another, orbital angular momentum eigenstates for coding possess higher information capacity.
车联网（IoVs）是物联网应用中最流行的技术之一。现有的车联网主要由公钥密码系统保护，该系统提供身份认证和信息安全。然而，使用所提出的肖尔算法，所有经典密码方案的安全性将暴露于未来的量子计算机技术之下。幸运的是，基于量子力学的无条件安全性，直接通信协议可以抵抗量子计算机攻击并直接传递秘密消息，而无需预共享密钥。对于车联网网络，我们提出了一种连续变量量子安全直接通信（CV-QSDC）协议，其中轨道角动量（OAM）被用作信息载体。一方面，连续变量量子通信系统领域与标准电信技术兼容；另一方面，用于编码的轨道角动量本征态具有更高的信息容量。
