Problems solved by technology

[0004] At this stage, the BIOS only completes the initialization operation of the root of trust, and does not verify the identity of the root of trust. Once the root of trust in the computer platform is replaced by an uncontrolled root of trust, the subsequent programs in the computer platform still access or Using this root of trust, the system cannot be known and controlled at the first time, which will threaten the data security on the computer platform

Abstract

The embodiment of the present invention discloses a method and system for controlling a trusted root in BIOS, including certificate initialization and certificate verification, certificate initialization includes generating a trusted root hardware platform certificate, importing the hardware platform certificate into the trusted root, and hardware platform The certificate includes the information subject and signature value; after the BIOS initializes the trusted root, it verifies that the information subject in the hardware platform certificate is valid, indicating that the hardware platform certificate matches the trusted root, ensures that the hardware platform certificate is valid, and verifies that the signature in the hardware platform certificate is valid , indicating that the hardware platform certificate matches the manufacturer's public key fixed in the BIOS, ensuring that the hardware platform certificate is legal. In the present invention, after the trusted root is initialized, the BIOS verifies the identity of the trusted root, and judges whether to provide the trusted root function for subsequent running programs according to the verification result, so as to protect the safety of computer upper layer application data.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to a method and system for controlling trusted roots in BIOS. Background technique [0002] Cryptographic security modules involve national information security, so countries have different requirements and restrictions on cryptographic security modules, and even only specific cryptographic security modules are allowed to be used in some important areas. The root of trust is a security component in the computer field, which can provide cryptographic functions for the computer system and protect information such as data in the computer platform. [0003] BIOS is the first program executed after the computer is powered on. It is responsible for the initialization operations of various hardware (such as graphics cards, sound cards, etc.), such as device detection, memory mapping, and other operations. The root of trust has a unified specification to constrain eac...
