摘　　要：近年来,随着物联网的快速发展,安全问题引起广泛关注,设备安全接入已经成为物联网领域的重要研究方向。针对目前物联网中设备安全接入技术存在复杂度高、不具有普适性、设备标识等信息易被追踪从而使接入设备遭到攻击等问题,提出了一种基于设备指纹的物联网设备安全接入方法。本文对设备指纹技术进行了改进,利用信息论中的信息熵与惊异值选取生成设备指纹的标识符,提高指纹的标识能力;同时设计了一套基于设备指纹的关联匹配算法。并以网络摄像头为例,搭建了实验环境,验证了该方法的有效性。In recent years,with the rapid development of the Internet of Things,security issues have attracted widespread attention,and device security access has become an important research direction in the field of Internet of Things.Aiming at the problems that the device security access technology in the Internet of Things is highly complex,not universal,and the device ID is easily traced to attack the access device,an IoT device based on device fingerprint is proposed.Secure access method.In this paper,the fingerprinting technology of the equipment is improved.The information entropy and surprise value in the information theory are used to generate the identifier of the fingerprint of the equipment,and the identification ability of the fingerprint is improved.At the same time,an association matching algorithm based on the fingerprint of the equipment is designed.Taking a webcam as an example,an experimental environment was set up to verify the effectiveness of the method.
