摘要
计算平台接入网络时的可信状态对网络安全具有重要的影响,为此可信计算组织TCG提出了TNC架构用以解决计算平台的可信接入问题,该架构提出了可信接入的模型和基本方法,已成为业界的研究热点。通过研究基于TNC架构的可信接入控制技术,实现了具有可信接入控制功能的可信交换机,并给出了可信接入控制应用解决方案,表明基于TNC的可信接入控制技术可以有效地从网络入口处防止非法或不可信终端给网络带来的潜在安全威胁。
The trusted state in computer＇s access to networks is of great importance for the security of the whole network. The TNC architecture proposed by TCG（Trusted Computing Group） could properly solve the trusted-access problem. This architecture provides the trusted-access model and its basic approach, and this is now a research hotspot in the industry. Based on study of trusted-access control technology based on TNC architecture, the trusted switch with trusted-access control is realized, and its application scheme is also given in this paper. It is indicated that the trusted-access control technology based on TNC could prevent potential threats by the illegal or trustless terminal from network entrance.
