Problems solved by technology

The premise of ensuring information security is that the information system itself is safe. If the system itself is tampered with by a malicious program at startup, the system will enter an untrustworthy state, resulting in the inability of the application program and the upper layer security mechanism based on this system. Faithful

Abstract

The invention provides a firmware security starting method and device, computing equipment and a readable storage medium, the method is applied to the computing equipment, and the computing equipment carries a common execution environment and a trusted execution environment; uEFI firmware runs in the common execution environment, at least one first calling interface is arranged in the common execution environment, and at least one second calling interface is arranged in the trusted execution environment; the method comprises the steps that when verification request information of a mirror image file is received, the verification request information of the mirror image file is transmitted to a second calling interface through a first calling interface, the verification request information is received through at least one second calling interface, the mirror image file is verified, and a verification result is obtained; and returning the verification result to the first calling interface through the second calling interface so as to execute the starting process of the UEFI firmware. According to the method and the device, the verification of the mirror image file in the trusted execution environment is realized, and the security of UEFI startup is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a firmware secure startup method, device, computing device and readable storage medium. Background technique [0002] UEFI (Unified Extensible Firmware Interface, Unified Extensible Firmware Interface) From a specification point of view, it is a specification that defines the interface specification between the computer operating system and platform firmware. From a physical point of view, BIOS (Basic Input Output System) and UEFI are two different types of computer firmware. Computer firmware is solidified in a non-volatile storage area (EEPROM) on the computer motherboard. For a small system, the computer starts it first, and then loads the real operating system. [0003] After the computer starts up and enters the configuration interface, what you can see intuitively is the UI interface of the UEFI firmware. You can configure the configurable items of this fi...
