Abstract: Embodiments of this application disclose a software integrity protection method and apparatus. A first device obtains a first software package, where the first software package includes a first signature made by a first party for a second software package by using a first private key; and the first device performs a signing operation on the first software package by using a second private key, to obtain a third software package including a second signature, where the first private key is controlled by the first party, and the second private key is controlled by a second party. The first device sends the third software package to a second device. The second device verifies the first signature and the second signature in the third software package respectively based on a first public key and a second public key that are prestored, to obtain a verification result.

Abstract: A software verification method and apparatus are provided. The method includes: reading flag information, where the flag information is used to indicate a target digital certificate; selecting one of a plurality of digital certificates as a target digital certificate based on the flag information, where the plurality of digital certificates include a first digital certificate and a second digital certificate, and the target digital certificate includes a cryptographic resource; and verifying software deployed on a device based on the cryptographic resource. Using the foregoing technical solution can ensure continuity of the software verification service in the device.

Abstract: This application discloses a method for performing secure boot based on a redundant cryptographic algorithm and a device. The method includes: obtaining first indication information and second indication information, and updating first baseline information based on the first indication information and the second indication information. The first indication information uniquely identifies a first cryptographic algorithm, the second indication information is used to instruct a network device to update the first cryptographic resource baseline information stored in a secure storage entity, and the first cryptographic resource baseline information is used to perform integrity verification on a first cryptographic resource used by the network device in a secure boot process.
