ATCA_STATUS | atcab_nonce_base (uint8_t mode, uint16_t zero, const uint8_t *num_in, uint8_t *rand_out) |
Executes Nonce command, which loads a random or fixed nonce/data into the device for use by subsequent commands. More... | |
ATCA_STATUS | atcab_nonce (const uint8_t *num_in) |
Execute a Nonce command in pass-through mode to initialize TempKey to a specified value. More... | |
ATCA_STATUS | atcab_nonce_load (uint8_t target, const uint8_t *num_in, uint16_t num_in_size) |
Execute a Nonce command in pass-through mode to load one of the device's internal buffers with a fixed value. More... | |
ATCA_STATUS | atcab_nonce_rand (const uint8_t *num_in, uint8_t *rand_out) |
Execute a Nonce command to generate a random nonce combining a host nonce (num_in) and a device random number. More... | |
ATCA_STATUS | atcab_challenge (const uint8_t *num_in) |
Execute a Nonce command in pass-through mode to initialize TempKey to a specified value. More... | |
ATCA_STATUS | atcab_challenge_seed_update (const uint8_t *num_in, uint8_t *rand_out) |
Execute a Nonce command to generate a random challenge combining a host nonce (num_in) and a device random number. More... | |
CryptoAuthLib Basic API methods for Nonce command.
The Nonce command generates a nonce for use by a subsequent commands of the device by combining an internally generated random number with an input value from the system.
