摘　　要：根据涉密存储介质保密管理的要求,以U盘为例,提出一种新颖的、以USB协议和大容量存储类协议为基础的移动存储介质管理架构。存储介质的唯一性标识由VID、PID和硬件序列号组成。同时还提出了基于CY7C67300嵌入式主机控制器的USB总线介质管理方案。通过USB总线枚举方式,逐一识别介质唯一性标识并通过超级终端显示。测试结果证明,该标识和识别方法可以用于移动存储介质安全管理系统,从而使涉密移动存储介质处于实时监控状态下,大大减少了泄密风险。According to the security management requirements to the rated mobile storage medium, a novel mobile storage medium security management architecture instanced by the U disk was proposed, which based on the USB and MSC specification. The unique identification was composed of VID, PID and hardware serial number. The scheme of USB medium management was provided, which based on the CY7C67300 EZ-HOST microprocessor. Through the USB enumeration the unique identifier information of U disk was obtained and it was displayed on the hyperterm program. The test results show that the unique information and identification method can be used for mobile storage medium security management system, so that rated mobile storage media were under real-time surveillance and control, which greatly reduced the confidential information leakage risk.
