摘要
为了提高目前嵌入式系统的安全性能,提出了一种针对嵌入式平台的安全设计方案。在研究了可信计算和嵌入式系统的技术基础上,提出通过扩展可信平台模块(TPM)的方法从底层对整个架构进行改进。在ARM嵌入式开发平台上,通过分析TPM芯片的低引脚数(LPC)接口功能,基于通用输入输出接口实现了TPM芯片在嵌入式平台上的扩展,并通过对平台启动代码的研究,设计并完成了该平台上的可信引导,整个过程验证了此设计方案的可行性。
To promote the security ability of currently embedded system,a secure scheme for embedded platform is put forward.Based on the study of trusted computing and embedded system technology,a method to improve the architecture from bottom up by extending the trusted platform module（TPM） is proposed.In the ARM embedded developing platform,after analyzing the low pin count interface function of TPM,the TPM extension to the platform is implemented via the general purpose input/outputinterface,also the trusted bootstrap on the platform is designed and complete based on the study of platform bootloader,the whole work validates the feasibility of this scheme.
