AES CCM request.
The AES CCM request primitive is issued by the AES user. There are two use cases for the request: The first one is to encrypt the user text with some given key. The second one is to decrypt the cipher text against the key. The encrypted or decrypted data is stored in text_data.
| uint8_t* sec_aes_ccm_req_t::auth_data |
Octet string representing input data to perform authentication.
| uint8_t sec_aes_ccm_req_t::auth_data_len |
Auth data length.
| uint8_t* sec_aes_ccm_req_t::key |
A 128-bit-long string to be used as a key. Each entity must have evidence that access to this key is restricted to the entity itself and its intended key sharing group member(s).
| uint8_t sec_aes_ccm_req_t::level |
Security level identifier.
| uint8_t* sec_aes_ccm_req_t::mic |
Counted authentication tag.
| uint8_t* sec_aes_ccm_req_t::nonce |
A nonce N of 15 - L octets. Within the scope of any encryption key, the nonce value must be unique.
| uint8_t* sec_aes_ccm_req_t::text_data |
An octet string representing plain text data in case of encryption and cipher text data in case of decryption.
| uint8_t sec_aes_ccm_req_t::text_data_len |
Text data length.
