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.
