摘　　要：可信网络接入使用可信计算技术来防止恶意终端访问受保护的网络,进而确保网络的安全,但目前可信网络接入系统都还存在一些安全和性能问题,影响其实际推广和使用。首先介绍可信网络接入的一些研究成果,然后基于这些研究工作总结出一个基本的网络接入模型和接入流程。通过对接入流程的分析,挖掘其可能存在的安全问题。最后针对这些安全问题,给出相应的改进方案。改进方案可以进一步加强网络接入系统的安全和性能,促进其推广使用。Trusted Network Access （TNA） can ensure the security of internal network by using trusted computing technology, which can prevent malicious terminals from accessing the protected network. However, current TNA systems have some security issues and performance problems, which influence their popularization and application. In this paper, firstly some researches are introduced, and then a basic network access model and process based on these researches are concluded. By analyzing the access process, possible security problems of TNA are found. Finally, the paper gives some improved research methods according to these security problems. Improved mechanisms can further strengthen the security and performance of TNA systems, and promote their use.
