REDUNDANT CRYPTOGRAPHIC ALGORITHM-BASED SECURE BOOT METHOD AND DEVICE

WIPO Patent Application WO/2021/232982

A1

Disclosed in the present application are a redundant cryptographic algorithm-based secure boot method and device. The method comprises: obtaining first indication information and second indication information, and updating first baseline information according to the first indication information and the second indication information. The first indication information is used for uniquely identifying a first cryptographic algorithm, the second indication information is used for instructing a network device to update baseline information of a first cryptographic resource stored in a secure storage entity, and the baseline information of the first cryptographic resource is used for performing integrity verification on the first cryptographic resource used by the network device in a secure boot process. Thus, by updating baseline information corresponding to a cryptographic algorithm, a network device can achieve the purpose of online adjusting the cryptographic algorithm for secure boot on the basis of different requirements, so that secure boot can be adaptively performed according to different security requirements, and the security of the network device is improved.
