Abstract
A cryptographic acceleration card included in a blockchain integrated station sends negotiation information to a provider of a new disk image, where the negotiation information is used by the provider to determine a deployment key, and where the new disk image is used to update an old disk image included in the blockchain integrated station. The cryptographic acceleration card receives a new hash value encrypted by the provider using the deployment key, where the new hash value corresponds to the new disk image. The cryptographic acceleration card replaces an old hash value corresponding to the old disk image with the new hash value, where the new hash value is compared with a current hash value of a disk image included in the blockchain integrated station to determine whether the disk image matches the new disk image.
