//! \section sec_aes Introduction
|
|
//!
|
|
//! The AES (advanced encryption standard) API provides access to the AES and key
|
|
//! store functionality of the crypto core. The SHA2 accelerator is also
|
|
//! contained within the crypto core. Hence, only one of SHA2 and AES may be
|
|
//! used at the same time.
|
|
//! This module offers hardware acceleration for several protocols using the
|
|
//! AES block cypher. The protocols below are supported by the hardware. The
|
|
//! driverlib documentation only explicitly references the most commonly used ones.
|
|
//! - ECB
|
|
//! - CBC
|
|
//! - CCM
|
|
//! - CBC-MAC
|
|
//! - GCM
|
|
//!
|
|
//! The key store is a section of crypto memory that is only accessible to the crypto module
|
|
//! and may be written to by the application via the crypto DMA. It is not possible to
|
|
//! read from the key store to main memory. Thereby, it is not possible to
|
|
//! compromise the key should the application be hacked if the original key in main
|
|
//! memory was overwritten already.
|
|
//!
|
|
//! The crypto core does not have retention and all configuration settings and
|
|
//! keys in the keystore are lost when going into standby or shutdown.
|
|
//! The typical security advantages a key store offers are not available in these
|
|
//! low power modes as the key must be saved in regular memory to reload
|
|
//! it after going into standby or shutdown.
|
|
//! Consequently, the keystore primarily serves as an interface to the AES accelerator.
