Problems solved by technology

Or a large number of customer server platforms need to be maintained in a unified manner. Manufacturers can perform off-the-shelf upgrades and separate maintenance through hardware refresh, storage media, etc., which obviously brings inconvenience to management.
Furthermore, in the process of firmware maintenance, if there are no necessary security measures, malicious attacks will bring serious consequences

Embodiment Construction

[0029] The content of the present invention is described in more detail below:

[0030] A capsule-type UEFI firmware remote management and control method based on BMC with security authentication of the present invention maintains UEFI firmware and encapsulates it with capsule-type rules, and has remote management and security authentication functions.

[0031] Encapsulate the UEFI BIOS data that needs to be changed according to the Capsule protocol, and establish communication with the UEFI BIOS platform through the BMC remote management platform on the resident server. After the BMC security authentication is passed, the data packet is sent to the client server platform. firmware system. Identify and analyze the Capsule data packet and encapsulate it into the PEI service. After the validity verification is passed, the driver is allocated and loaded in the DXE stage of UEFI, the firmware is updated and written, and the system restarts after the modification is completed.

Abstract

A method for remote management and control of capsule UEFI firmware based on BMC with safety authentication belonging to the field of computer system firmware security technology, The invention encapsulates and updates the data according to the Capsule protocol, and performs the designated module and the overall management control on the client UEFI firmware through the remote management and control mode of the BMC platform, at the same time, the safety authentication process is added, the firmware security is strengthened, and the maintainability of the firmware system is improved.

Description

technical field [0001] The invention relates to computer system firmware security technology, in particular to a capsule UEFI firmware remote management and control method based on BMC with security authentication. Background technique [0002] UEFI Unified Extensible Firmware Interface is a defined set of interfaces and data structures between platform firmware and operating system. With the rapid development of UEFI BIOS, the application is becoming more and more popular, and the maintainability and security requirements of UEFI BIOS are also getting higher and higher. [0003] The UEFI boot process includes SEC (security sets the protection mode of the CPU), PEI (initializes PEI before EFI), DXE (executes the driver, installs the Device handle, installs the protocol), BDS (boot device selection), TSL (temporary system loading ), RT (Run Time) and other stages. UEFI programs are divided into three categories: kernel, driver and application. The UEFI kernel provides serv...
