首发时间:2021-03-23
摘要:车联网中车辆在公开信道进行信息传输,无法保证用户身份的可信性和通信内容的安全性。物理层安全技术利用无线信道的特殊属性来增强无线网络的安全性。本文首先介绍了物理层安全技术的基本原理,为基于雷达通信一体化的物理层加密信号的生成做铺垫。然后提出将物理层安全技术利用在车载雷达通信一体化中,通过物理层密钥形成密钥信息,加载到雷达通信一体化信号上,实现用户身份信息的验证和通信信息的加密。仿真结果表明该方案能够保证通信的安全性,并且该信号具有近似图钉型的模糊函数,满足雷达探测波形的需求。

Physical layer encryption scheme based on radar communication integration
Abstract:In the Internet of vehicle, vehicles transmit information in the open channel, which can not guarantee credibility of user identity and security of communication content. Physical layer security technology uses special properties of wireless channel to enhance security of wireless network.Firstly, this paper introduces basic principle of physical layer security technology, which lays the groundwork for the generation of physical layer encryption signal based on radar communication integration. Then, physical layer security technology is used in the integration of vehicle-borne radar communication. The key information is formed by physical layer key, which is loaded on the radar communication integration signal to realize verification of user identity information and encryption of communication information. The simulation results show that the scheme can ensure the security of communication, and this signal has similar thumbtack ambiguity function, which can meet the needs of radar detection waveform.
