Abstract

The invention discloses a trusted starting method of embedded equipment based on an embedded trusted computing module. Based on a trusted computing theory, combined with the characteristics of embedded equipment, and on the premise that the system structure of the embedded equipment is not changed, the embedded trusted computing module is designed, a trusted starting mechanism suitable for the embedded equipment is provided, U-boot (one type of Bootloader) is subjected to trusted transformation to achieve the functions of sending files and controlling kernel starting, the Bootloader is measured by the embedded trusted computing module before being operated, the kernel is measured before being started by using the Bootloader, and a system is continuously subjected to trusted reporting and program and related data checking after being started.

Description

technical field [0001] The invention relates to the field of trusted computing for embedded devices, in particular to a trusted startup method for embedded devices based on an embedded trusted computing module. Background technique [0002] With the advent of the information age and the rapid expansion of information interaction, mobile smart platform devices have played an increasingly important role in production and life with their good portability and high-quality interactivity. Most mobile smart devices use Embedded operating systems, currently using mobile terminals to access the Internet, transactions and real-time communications have become a trend. Not only that, there are also a large number of embedded platform applications in industrial control, and the security problems brought about by this have gradually made People are aware of the seriousness of the problem, and a large number of embedded devices will face more and more serious security challenges in the tre...
