摘　　要：基于可信计算中一级校验一级的思想,针对VxWorks嵌入式操作系统的特性,介绍了一种实现VxWorks嵌入式操作系统的可信启动的方法。通过建立一条链式信任链,使用转换模块结合TCM芯片的方式设计并实现了一种安全增强的可信硬件平台,实现了对VxWorks嵌入式平台的可信启动的控制,介绍了平台的硬件与软件的设计与实现方式。通过对本设计的功能性测试,证明设计并实现的可信平台可抵御外部威胁对平台信息的篡改,增强硬件平台的安全性。In view of the idea of level calibration level in trusted computing and the characteristics of VxWorks embedded operat- ing system,this paper introduces a method of implementing the trusted boot of VxWorks embedded operating system.By establishing a trusted chain,a secure enhanced trusted hardware platform is designed and implemented by incorporating conversion module and TCM chips. The trusted boot of VxWorks embedded platform is implemented.The hardware and software design and implement methods of platform are introduced.The functional test results show that the trusted platform can defense the violence for platform information from external threat and enhance the security of hardware platform.
