基于USBKey和BSP的嵌入式系统安全方案

Security scheme of embedded system based on USBKey and BSP

针对目前嵌入式系统安全机制多采用单一口令的不足,提出了一种在VxWorks环境下基于USBKey和BSP的安全解决方案。该方案通过分析VxWorks BSP的功能及启动机制,在BSP中实现了基于USBKey的身份认证,同时使用USBKey实现对系统正常运行期间的安全保护。

This paper presented a security scheme based on USBKey and BSP in VxWorks, in allusion to the deficiency of the single password which was often as the security mechanism in embedded system. The scheme implemented the authentication based USBKey in BSP by researching the function and startup mechanism of VxWorks BSP. Meanwhile, through the USBKey, it implemented the security safeguard during the running of system.
