Detailed Description

Structure encoding IO parameters in AEAD (Authenticated Encryption with Associated Data) scenario like in CCM.

App has to furnish valid contents prior to making cipher_ccm_op() call.

Field Documentation

ad

uint8_t* cipher_aead_pkt::ad

Start address for Associated Data.

This has to be supplied by app.

ad_len

uint32_t cipher_aead_pkt::ad_len

Size of Associated Data.

This has to be supplied by the app.

pkt

struct cipher_pkt* cipher_aead_pkt::pkt

tag

uint8_t* cipher_aead_pkt::tag

Start address for the auth hash.

For an encryption op this will be populated by the driver when it returns from cipher_ccm_op call. For a decryption op this has to be supplied by the app.
