Abstract: A component authentication method includes, after a computer is powered on, a baseboard management controller (BMC) in the computer sends an authentication request to one component in the computer, to initiate access authentication on the component. The component sends an access request to the BMC, where the access request carries an access authentication certificate of the component. After verification on the access authentication certificate of the component succeeds, the BMC sends an access response to the component such that, before the component is booted, the BMC verifies the access authentication certificate of the component, and the component is allowed to be booted only if the verification succeeds.
