A method for controlling secure boot of a board is disclosed, including: after the board is powered on, obtaining a re-signature of a software package to be loaded to the board, where the re-signature of the software package is obtained by using a board private key of the board to re-sign the software package, the re-signature is performed after an original signature of the software package passes a verification performed by using a software package public key of the software package, and the original signature is obtained by using a software package private key of the software package to sign the software package; using a board public key pairing with the board private key to check a re-signature of the software package; and booting the board after the re-signature passes the check. The method ensures other boards can securely boot when a key pair in a software package is leaked.
