Detailed Description

Aead component.

The mcuxClAead component implements the Authenticated Encryption with Associated Data (AEAD) operations supported by CLNS.

An example of how to use the mcuxClAead component can be found in /mcuxClAead/ex.

The mcuxClAead component supports interfaces to either authenticate and encrypt or verify and decrypt a message in one shot (mcuxClAead_crypt) or to either authenticate and encrypt or verify and decrypt it in parts (mcuxClAead_init, mcuxClAead_process, mcuxClAead_process_adata and mcuxClAead_finish). In case of processing a message in parts, first an initialization has to be performed (mcuxClAead_init), followed by zero, one or multiple updates (mcuxClAead_process_adata and mcuxClAead_process), followed by a finalization or verification (mcuxClAead_finish/mcuxClAead_verify). The finalization generates the output tag and destroys the context. The verification generates and compares the output tag and destroys the context. After the finalization/verification step, no further updates are possible.

The targeted AEAD algorithm is selected by passing one of the offered algorithm mode descriptors (mcuxClAead_Modes), which are listed in file mcuxClAead_Modes.h
