摘　　要：研究针对现有的操作系统安全机制无法对USB设备底层固件进行安全检测并防护的问题,在对各种防御手段进行比较研究的基础上,探讨了如何监测和预防HID恶意攻击行为。基于STM32F03单片机,设计了一种能够自动监测USB设备并及时拦截HID攻击的硬件外设,设计并优化该设备的防护算法,最后针对性进行防护测试实验。实验结果表明该设备在不影响USB设备正常运行的前提下,在必要的时候能够实施高效的、自动的拦截,从而保护计算机与其内部文件的安全。Aiming at the issue that existing operating system security mechanisms can not securely detect and protect the underlyingfirmware of USB devices,this research explores how to monitor and prevent HID malicious attack behavior based on a comparative research on various defense means.Based on the STM32F03 single-chip microcomputer,it designs a hardware peripheral that can automatically monitor USB devices and intercept HID attacks in a timely manner.The protection algorithm of the device is designed and optimized,and targeted protection testing experiments are conducted.The experimental results show that the device can implement efficient and automatic interception when necessary without affecting the normal operation of USB devices,thereby protecting the security of the computer and its internalfiles.
