基于嵌入微LINUX的开机安全认证系统

Boot Security Authentication System Based on Embedded Micro-LINUX

提出了一种高安全性的开机安全认证方法,该认证系统在硬盘上嵌入一个微Linux系统作为认证系统的载体,并且使用USB移动介质作为KEY盘来保存硬盘启动扇区、分区表、以及登录密钥等系统启动的必要信息,只有同时拥有密钥和KEY盘的合法用户才能通过验证并登录计算机系统.这种方法实现了重要信息如密钥和启动信息等与硬盘原始数据的独立存储,而且可以应用基于微Linux系统下性能优良的MD5和DES等加密算法,从而增强了开机认证的安全性.

This paper proposes a highly secure method of boot security authentication, involving one embedded micro-Linux system stored in the disk driver being the authentication carrier and one USB removable media being a KEY startup disk to save boot data and key disk. This approach implemented the independent storage of important information such as key, start-up and disk original data. Also, it can employ high-performance MD5 and DES encryption algorithms based on micro-Linux system, thus greatly increasing the security of the boot authentication and effectively protecting the disk data.
