摘　　要：文章给出了一种对连网计算机硬盘信息进行安全访问的隔离卡实现方案,介绍了基于PCI总线的双硬盘隔离卡的组成及工作原理,详细讨论了其硬件设计。This paper proposes an implementation scheme of isolating card, which can assure the secure access to hard disk data of network-connected computer. It also introduces the structure and work principle of the PCI-based isolating card, and discusses the hardware design of this card. This solution adopts the transparent-to-user physical isolation technology and the network connection control technology, and it can protect the hard disk data of network-connected computer effectively.
