Endogenous Secure Communication Based on Characteristics of Wireless Channel

伴随着信息技术的高速发展,无线通信网络的安全形势日益严峻。数以亿计的设备接入无线通信网络中,针对用户隐私以及基础网络环境的窃听、攻击事件频频发生,无线通信网络的安全问题已成为限制无线通信业务广泛开展的严重障碍。传统认证与加密机制与传输相脱离,以密码算法和分发密钥的私密性为前提,容易受到物理层的攻击。为此,迫切需要深入开展面向物理层的安全机制研究。从无线通信网络的根源出发,面向无线信道的内生属性,研究了基于无线信道特征的内生安全通信架构,并针对此架构提出了基于射频指纹与信道密钥的内生安全通信技术方案。该架构将认证、加密与传输融为一体,从体系结构上增强了防御效果;利用无线信道特征的内生特点,从技术手段上提高了安全性能。

With the rapid development of information technology,the safety of wireless communication network is increasingly severe.Millions of devices access to the wireless communication network.In view of user privacy,eavesdropping and attacks in the basic network environment,the security problem of wireless communication network has obviously become a serious obstacle to the widespread development of wireless communication business.Traditional authentication and encryption mechanism is separated from transmission,which is based on the privacy of cryptographic algorithm and key distribution.However it is easy to be attacked in the physical layer.Therefore,it is urgent to carry out in-depth research on the physical layer oriented security mechanism.Based on the endogenous attribute of wireless channel,this paper studies the endogenous secrecy communication architecture based on the characteristics of wireless channel,and proposes an endogenous secure communication technology based on radio frequency(RF)fingerprint and secret key generation.The architecture integrates authentication,encryption and transmission,enhances the defense effect from the architecture,and improves the security performance from the technical means by using the endogenous characteristics of wireless channel characteristics.
