基于虚拟磁盘的可信加密磁盘的研究与实现

Trusted Eencryption Disk Research and Implementation Based on Virtual Disk

文章分析了磁盘加密软件Truecrypt,分析了其透明加解密的原理。同时文章还介绍了可信计算的基本思想。在基于虚拟磁盘管理技术及实时加解密磁盘软件Truecrypt的基础上,结合可信计算的思想,利用USBKEY作为可信的硬件基础,设计了采用USBKEY的可信磁盘加密系统。通过使用USBKEY作为可信的硬件基础实现加密磁盘的可信性。

This paper analyzes the disk encryption software Truecrypt, analyzes its the principle of transparent encryption and decryption. At the same time, this paper also introduces the basic idea of trusted computing. Based on the disk encryption software Truecrypt of the virtual disk management technology and real-time encryption and decryption, combined with the idea of trusted computing, using USBKEY as the trusted hardware foundation,design using USBKEY trusted encryption disk system. Through the use of USBKEY as a trusted hardware basic to make encrvption disk trusted.
