摘要
为了解决目前嵌入式应用中存在的诸多安全问题,设计了一种基于TPM(Trusted Platform Module)安全芯片的嵌入式平台设计方案。在分析可信计算技术发展的基础上,结合嵌入式平台结构特点以及TPM芯片的常见接口,采用了通过I2C总线扩展TPM的方法。最后讨论了TPM的操作方法,设计了TPM在Bootloader和Linux内核两种环境下驱动程序。
In order to solve the security problems existing in the current embedded applications, an embedded platform design scheme is presented based on TPM （Trusted Platform Module）. Based on the analysis of the development of trusted computing technology and the normal interface of TPM, TPM is extended by I2C interface. After studying the method of TPM operation, TPM drivers for Bootloader and Linux kernel are designed.
