Research on the Design and Realization of Trusted Boot Architecture Based on Embedded System
摘要
Abstract
This paper analyzes and researches the boot process of embedded system and proposes a trusted boot method based on Raspberry Pi embedded system.The method adopts STM32F103RCT6 controller in hardware to realize the basic functions of trusted computing module such as SHA-256 encryption algorithm,non-volatile storage space,and so on,and uses this as the hardware trusted root.Meanwhile,a peripheral boot control circuit is designed to connect the Raspberry Pi TF card and the system power supply in order to realize the Raspberry Pi boot process control,so that the controller can actively read the Raspberry Pi boot file,kernel image,and other files in the operating system located in the TF card to realize the active metrics,and to verify the results of the metrics.It is verified that the system successfully measures the boot file and completes the trusted boot of Raspberry Pi.The trusted boot method proposed in this paper can be compatible with the trusted computing 3.0 dual architecture proposed independently in China,and provides a reference for the implementation of trusted boot for other embedded devices.关键词
