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 of associated data.

The buffer is supplied by the application and must remain valid for the duration of the operation.

◆ ad_len

uint32_t cipher_aead_pkt::ad_len

Size of associated data, in bytes.

◆ pkt

struct cipher_pkt* cipher_aead_pkt::pkt

Packet containing input and output buffers.

This is supplied by the application and must remain valid for the duration of the operation.

◆ tag

uint8_t* cipher_aead_pkt::tag

Start address of the authentication tag buffer.

For encryption, the driver writes the tag to this application allocated buffer before the operation completes. For decryption, the application supplies the expected tag in this buffer.
