ENCRYPTION AND DECRYPTION PROCESSING METHOD, APPARATUS, AND DEVICE

摘要

An encryption processing method includes: generating, by a device itself, a key pair, where the key pair includes a first key used for encryption and a second key used for decryption; storing, by the device, the key pair in a first storage space; performing, by the device, digest calculation on device running data to obtain a digest of the device running data, where the device running data is stored in a second storage space; and reading, by the device, the first key from the first storage space, and encrypting a digest of the device running data with the first key to obtain a first digital signature.

主权项

1. A device, comprising a processor and a storage, wherein: the storage comprises a first storage space and a second storage space, wherein the first storage space does not provide any external access; and
the processor is configured to: generate a key pair by itself, wherein the key pair comprises a first key used for encryption and a second key used for decryption; store the key pair in the first storage space; perform digest calculation on device running data to obtain a digest of the device running data, wherein the device running data is stored in the second storage space; read the first key from the first storage space; and encrypt the digest of the device running data with the first key to obtain a first digital signature.
