Abstract
A data encryption and decryption system a host system, sequencer, hardware processor, direct memory access modules, and cryptography engines having input and output buffers, and symmetric encryption/decryption and digest algorithm modules. The host system determines encryption/decryption calculation and/or digest calculation method, and generates corresponding encryption/decryption and/or digest calculation commands. The sequencer analyzes the encryption/decryption and/or digest calculation commands to generate control flow commands, and controls one or more of the direct memory access modules via the control flow commands to input data to be encrypted/decrypted into the input buffer of one or more cryptography engines. The hardware processor controls the symmetric encryption/decryption algorithm module to perform encryption/decryption calculations according to the encryption/decryption calculation commands, and/or, controls the digest algorithm module to perform digest calculations on data to be encrypted/decrypted according to the digest calculation commands, and sends calculation results to the host system by the direct memory access module.
