摘　　要：万物互联的智慧生活渐行渐近,物联网设备的安全问题也与日俱增,成为制约其进一步发展的瓶颈。传感器作为物联网设备中获取外界环境信息的主要手段和途径,面临着各种带外信号注入攻击的威胁。本文针对惯性传感器的带外信号注入攻击,提出了一种攻击检测与校正方案。此方案以冗余组件为基础,利用惯性传感器带外信号注入攻击数字化过程中的混叠现象,检测惯性传感器输出结果的正确性,并能对异常信号进行校正。系统仿真与实验结果表明,该方案能正确地检测到攻击者注入的带外信号,并能有效地滤除攻击产生的传感器异常数据输出,从硬件层面上解决带外信号注入攻击对惯性传感器的恶意影响。Intelligent life with Internet of Things(IOT)is gradually approaching,and security problems of the IOT devices are also increasing,limiting the further development.As the main mean and way to obtain the external environment information in IOT devices,sensor is facing the threat from various out-of-band signal injection attacks.In this paper,a detection and correction scheme for the out-of-band signal injection attack of inertial sensors is proposed,where the redundant component is the ba-sis and the aliasing phenomenon in digitization process during the attack injection is utilized to detect the accuracy of the inertial sensor output result and to correct the abnormal signals.System simulation and experiment results show that the proposed scheme could correctly detect the out-of-band signal in-jected by the attacker,and effectively filter out the sensor abnormal data output generated by the at-tack,addressing the malicious impact of out-of-band signal injection attack on the inertial sensor in the hardware.
