基于USBKEY的访问控制方法研究

Research on access control methods based on USBKEY

为了使USBKEY得到更广泛的利用,分析了目前几种不同环境下基于USBKEY访问控制的方法,介绍了各自的工作原理并对各种访问控制方式的优点和缺点进行了比较。在此基础上,提出了在BIOS层实现的基于USBKEY的远程访问控制框架,对USBKEY用户登录系统过程中身份认证和系统资源的访问控制功能进行完善。

For wide use of USBKEY, some actual methods of USBKEY-based access controls in different environments are analyzed, and the elements of them are introduced. The strengths and weaknesses of the access control methods are compared. On the basis of this, a remote USBKEY-based access control frame which implemented in BIOS is designed. The access control fimction of identity authen- tication and system resource is improved in USBKEY user load system.
