Abstract

The embodiment of the invention provides a trusted UEFI firmware recovery method and device, a medium and equipment, and belongs to the technical field of trusted computers. The method comprises the steps that trusted firmware reads UEFI firmware compressed data from a trusted read-only area of a firmware memory to a trusted computing memory area; the trusted firmware decompresses the UEFI firmware compressed data to obtain decompressed UEFI firmware; the trusted firmware copies the decompressed UEFI firmware to a universal computing memory area; the trusted firmware measures the UEFI firmwarecopied to the universal computing memory area; and after the measurement is passed, the trusted firmware enables the universal computing core to start the UEFI firmware in the universal computing memory area to complete UEFI firmware recovery. According to the technical scheme provided by the embodiment of the invention, the recovery efficiency and safety of the UEFI firmware can be improved under the condition that the UEFI firmware is damaged through a trusted environment.

Description

technical field [0001] The present disclosure relates to the technical field of trusted computers, in particular, to a trusted UEFI firmware recovery method, recovery device, computer storage medium and electronic equipment. Background technique [0002] With the continuous maturity of UEFI (Unified Extensible Firmware Interface, Unified Extensible Firmware Interface) technology, the traditional computer BIOS (Basic Input Output System, Basic Input Output System) technology is gradually being replaced by UEFI technology. In the field of trusted computer technology, It is the trend to install the operating system using UEFI technology. Although UEFI technology has the advantages of strong interoperability, short startup time, and strong compatibility, it still suffers from damage due to attacks. In a related field, the above problems can be solved by using a technique of restoring UEFI firmware. In related technologies, the technology of recovering UEFI firmware needs to se...
