Abstract

The invention provides a computer starting method, and a trusted root is arranged in a CPU of a computer, and the computer starting method comprises the following steps: after the computer is poweredup, executing a program code of the trusted root; enabling the trusted root to verify the signature of the basic firmware of the computer; when the trusted root successfully verifies the signature ofthe basic firmware, executing a current program code of the basic firmware to enable the basic firmware to complete initialization of hardware of the CPU; enabling the basic firmware to perform signature verification on third-party firmware of the computer; when the basic firmware successfully verifies the signature of the third-party firmware, executing the current program code of the third-partyfirmware, so that the third-party firmware loads the operating system of the computer. According to the invention, the security of the computer system can be enhanced.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a method for starting a computer. Background technique [0002] Computer startup security is crucial to the security of the entire computer system, and it is the basis for other security mechanisms of the system to function. In the traditional computer startup method, the central processing unit (CPU, Central Processing Unit) does not verify the startup program code and user data. Hackers and other attackers can seize the execution authority of the CPU by tampering with the program code, load malicious programs, obtain User data, threatening computer system security. Contents of the invention [0003] The invention provides a method for starting a computer, and the purpose is to solve the problem of low security of the computer system during the starting process of the computer. [0004] In order to achieve the above object, the embodiment of the present invention p...
