摘 要: | 在分析了全盘加密中实施PBA系统重要性的基础上,介绍了PBA系统的功能结构,但是PBA系统在使用BIOSAPI后没有刷新内部的键盘缓;中区,存储在键盘缓冲区的用户密钥容易遭受攻击。为解决这个问题,本文提出了一种在PBA系统中采用动态令牌和Usbkey的安全登录认证模式,有效的防止通过各种手段盗取用户密钥后实施的重放攻击,弥补了Microsoft Bitlock磁盘加密软件在这方面的缺陷。

Abstract: | On the basis of analyzing the importance of PBA in full disk encryption system, the functional structure is introduced, whereas PBA system typically uses the BIOS API without flushing the BIOS internal keyboard buffer, the user key will be easy to be attacked. To address the problem a secure Iogon authentication mode is introduced in this article, it bases on dynamic token and Usbkey in the PBA system, and it can effectively avoid multi-sending attack and make up deficiency of the Microsoft Bitlock software. |

Keywords: | full disk encryption pre-boot authentication dynamic token Usbkey Iogon authentication |
