摘　　要：针对嵌入式终端的安全问题日益突出以及嵌入式终端信任链传递不完整等问题,结合可信计算的思想,提出了自底向上的和自顶向下的嵌入式可信终端信任链传递模型。基于该模型,以linux嵌入式系统平台为原型,设计了启动可信,操作系统加载可信以及应用程序的加载可信。可以较好地解决目前嵌入式终端面临的安全问题。To solve the problems that the embedded terminal has increasingly severe security problem and the transfer of embedded terminal trusted chain is incomplete,a bottom-up and top-down transfer model of the trusted chain of embedded trusted terminal is presented in the paper combining with the idea of trusted computing.Based on this model,we designed booting trust,loading trust on operating system and on applications with the prototype of Linux embedded system platform.These can well solve to a certain extent the security problems the current embedded terminal encountering.
