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.

Abstract: An integrity verification method includes: a first device that sends first data to a second device. The first device sends an integrity measurement baseline value corresponding to the first data to a verification server, and the second device sends an integrity measurement value corresponding to the first data to the verification server. The verification server performs integrity verification on the first data based on the integrity measurement value and the integrity measurement baseline value.

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: 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: This application discloses a software loading method, applied to a network device on which software is deployed. In the method, a software version identifier is indicated by using a version file, and when loading software, the network device compares a version identifier of to-be-loaded software with the version identifier in the version file, to determine whether a version of current to-be-loaded software is a secure version. This implements protection of a software loading process.
