摘　　要：对于计算机信息系统受到攻击基本上可以分为基于CPU和I/O控制器这两种。对于CPU的攻击已经被深入研究,各种成熟的对策也被广泛的应用。但是对于I/O控制器攻击的研究非常缺乏有效的保护机制。为了研究关于I/O控制器的攻击,使用FPGA可编程技术设计和实现了一款PCI Express总线的平台。平台能产生任意种类的关于PCI Express事务层的信息包,为研究各类I/O控制器的攻击提供了基础。The attacks on those computer information systems can be basically categorized into based on the CPU and based on the I/O controller. Attacks based on the CPU have been well studied, and many mature countermeasures have been largely implemented. However, attacks based on the I/O controller have been less studied, and few effective protection mechanisms exist. In order to deal with the attacks based on the I/O controller, a platform based on the FPGA programmable technology has been designed and implemented using PCI Express bus. This platform has the capability of generating any kind of packet at the transaction layer of PCI Express, and it provides a basic platform for the researches over the malicious actions based on the I/O controller.
