摘要
针对使用USB存储设备所引发的信息安全问题,提出了一种基于嵌入式Linux系统的USB存储设备访问控制方案。该方案在保持主机系统软硬件结构不变的基础上增加了嵌入式Linux平台,并利用Linux USB从设备端驱动,在嵌入式平台中实现了对USB存储设备的访问控制;同时结合用户实际需要,采用基于角色的访问控制方式,给出了详细的设计思路和软硬件框架。试验结果表明,该方案可以有效地防范针对USB接口存储设备的攻击,从而达到保障用户信息安全的目的。
Aiming at the information security problem occurs in applying USB storage devices, the access control scheme based on embedded Linux system is proposed. Keeping the structure of software and hardware of the main system unchanged, the embedded Linux platform has been added. Adopting Linux USB driver from device side, access control of USB device is implemented on embedded platform. In addition, combining users＇ needs, the role-based access control mode is used. Detail design concept and frameworks of software and hardware are given. The result of experiments indicates that this scheme effectively prevents the attacks against the USB storage device, and achieves the purpose of protection of information security for users.
