一种嵌入式平台身份认证可信网络连接模型设计

Design of Trusted Network Connection Model for Identity Authentication of Embedded Platform

在研究嵌入式设备通信安全性与可靠性问题的基础上,针对目前网络安全通信措施存在的众多不足,提出了一种应用于嵌入式平台的基于802.1x的可信网络连接认证模型,并利用开源软件libtnc和TNC@FHH对以加入可信模块的ARM开发板为TNC客户端,以基于MIPS架构的国产安全可信计算机PT-1500为TNC服务器组成的嵌入式系统进行了实验测试,以添加非法设备的方式验证本设计的实用性及安全性.测试结果表明,该方案能有效地完成嵌入式平台身份验证、平台完整性认证及信息安全传输.

Based on the study of the security and reliability of embedded devices,puts forward a 802.1x-based trusted network connection authentication model for embedded networks based on the shortcomings of the current network security communication measures.And uses the open source software libtnc and TNC @ FHH to the to join the trusted module of the ARM development board for the TNC client,based on the MIPS architecture of the domestic security trusted computer PT-1500 for the TNC server composed of embedded systems for experimental testing,and verify the authenticity and safety of the design by adding illegal equipment.The test results show that the model can effectively complete the embedded platform authentication,platform integrity certification and information security transmission.
