Embodiment Construction

[0016] A hardware interface for firmware security management, the hardware interface is used for the computer to access the security detection module in the startup phase, call the security verification function, and measure and verify the integrity of key hardware devices and operating system core files;

[0017] The process of the computer calling the safety detection module through the hardware interface is: calling and opening the device interface to realize access to the safety detection module; after the access is successful, the interface program stored in the safety detection module is loaded into the memory through the safety detection program loading interface ;Call the trusted verification interface to realize the setting, updating, deletion of the expected value and the verification of the data to be verified; finally exit the access by closing the device interface, and release the relevant resources.

[0018] According to the above hardware interface and the conten...

Abstract

The invention discloses a hardware interface used for firmware safety management and belongs to the technical field of firmware management. The hardware interface is used for having access to a safety detection module during the start stage of a computer, a safety verification function is called, and integrity of key hardware devices and operation system core documents are measured and verified; a hardware layer interface is provided for a credible module according to firmware safety, a firmware path is set when the device is initially powered on, the device can be normally started through safe verification, and that is, the aim of providing beneficial guarantee for safety of computer firmware is achieved through the hardware interface.

Description

technical field [0001] The invention discloses a hardware interface for firmware security management, which belongs to the technical field of firmware management. Background technique [0002] With the development of electronic information technology, the application field of computer has penetrated into all walks of life in society, changing the traditional work, study and life style, and promoting the development of society. Due to the characteristics of fast calculation speed and high calculation accuracy, multi-architecture and multi-platform computer equipment play an important role in daily work, life and production. Therefore, the security of computer equipment has attracted more and more attention. The introduction of various types of security software ensures the software security of devices, but most security software functions based on the operating system, and it is difficult to provide help for the security of computer firmware. [0003] Aiming at this situati...
