This manual makes frequent use of certain terms. These terms refer to structures that the crypto core uses for operations.
External memory: A memory that is externally attached to the crypto core AHB master port, and only accessible using DMAC operations. This is memory external to the module, not memory external to the MCU.
Slave interface (host processor bus): Interface of the AES and Hash Cryptoprocessor that the host processor uses to read or write registers of the module.
Tag or digest: Two interchangeable terms that indicate the result of an authentication operation. The term digest is used for regular hash operations, while MAC is used for authenticated encryption operations (AES-CCM, AES-GCM), and MAC operations (CBC-MAC).
Crypto context: A collection of parameters that define the crypto operation: mode, key, IV, and so forth.
