摘　　要：5G时代,大量物联网无线终端设备接入网络。无线网络的开放性,使其容易遭受各种攻击。认证通常是安全通信的第一道防线,用于识别发送方和接收方的身份和消息真伪。目前,应用于通信系统的认证存在几个问题:采用传统基于密码的认证不适用于轻量级设备,无法大规模应用于物联网终端;很多认证通常机制单一且不适用移动终端。针对上述问题,提出物联网中移动终端的协同身份检测机制。具体地,采用物理层认证适用于轻量级设备,并结合基于射频指纹和信道信息的认证机制,对移动终端的身份和数据均进行认证,旨在实现轻量级、更安全、更大范围的认证。In the era of5G,a large number of wireless terminal devices connected to the Internet of things are connected to the network.The openness of the wireless network makes it vulnerable to various attacks.Authentication is usually the first line of defense for secure communications to identify the identity and message authenticity of the sender and receiver.At present,there are several problems in the authentication of communication systems:The traditional password based authentication is not suitable for lightweight devices,and cannot be used in the Internet of things terminal on a large scale.Many authentication mechanisms are usually single and do not apply to mobile terminals.In view of the above problems,a cooperative identity detection mechanism for mobile terminals in the Internet of things is proposed.Specifically,physical layer authentication is suitable for lightweight devices,and combines the authentication mechanism based on radio frequency fingerprint and channel information to authenticate the identity and data of mobile terminals,aiming to achieve lightweight,safer and wider range of authentication.
