Problems solved by technology

[0003] In the existing chain of trust technology, the trusted platform module (TPM) is used as the root of trust to detect the integrity of EFI and build a chain of trust to start the server. During this process, the root of trust will be loaded into the memory, resulting in a Likelihood of being compromised, making the root of trust less trustworthy

Abstract

The invention provides a trust chain construction method and apparatus. The method comprises the steps of marking out a security storage space for an ARM processor and storing hardware information as a root of trust in the security storage space; starting a TPM (Trusted Platform Module) based on the root of trust, performing a power-on self-test, and determining that the TPM is available; by utilizing the TPM, measuring codes and data of an initialization module of an EFI (Extensible Firmware Interface) and a server from a power-on stage to an operating guide stage; verifying whether the codes and the data of the initialization module of the EFI and the server from the power-on stage to the operating guide stage are complete or not, and if yes, loading the codes and the data of the initialization module of the EFI and the server from the power-on stage to the operating guide stage; measuring drive files and device files in a drive execution environment and a drive program by utilizing the codes of the initialization module of the EFI and the server from the power-on stage to the operating guide stage; and verifying the completeness of the drive files and the device files. According to the scheme provided by the method and apparatus, the credibility of the root of trust is effectively improved.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a trust chain construction method and device. Background technique [0002] The Extensible Firmware Interface (EFI), as an upgrade solution for the Basic Input and Output System (BIOS), stores the computer's basic input and output programs, system setting information, self-test programs after power-on and system self-starting programs, and provides the computer with the lowest level. , The most direct hardware setting and control, making EFI often attacked by viruses and Trojan horses. At present, the integrity of EFI is mainly detected through the trust chain technology of trusted computing, that is, to detect whether EFI is damaged. [0003] In the existing chain of trust technology, the trusted platform module (TPM) is used as the root of trust to detect the integrity of EFI and build a chain of trust to start the server. During this process, the root of trust will ...
