Abstract
The present disclosure provides a data encryption method, applied to a processor in a cryptographic device, where the cryptographic device includes a first storage module, and the method includes: receiving to-be-processed data sent by a server, and distinguishing critical data and non-critical data in the to-be-processed data; performing encryption processing on the critical data in the to-be-processed data to obtain encrypted critical data; and writing the encrypted critical data and the non-critical data into the first storage module to enable a client to read data from the first storage module.
