A struct containing all of the function pointers needed to implement cipher operations using secure elements.

PSA Crypto API implementations should populate instances of the table as appropriate upon startup or at build time.

If one of the functions is not implemented (such as psa_drv_se_cipher_ecb_t), it should be set to NULL.

Public Functions#

size_t
MBEDTLS_PRIVATE(context_size)

The size in bytes of the hardware-specific secure element cipher context structure.

psa_drv_se_cipher_setup_t
MBEDTLS_PRIVATE(p_setup)

Function that performs a cipher setup operation.

psa_drv_se_cipher_set_iv_t
MBEDTLS_PRIVATE(p_set_iv)

Function that sets a cipher IV (if necessary)

psa_drv_se_cipher_update_t
MBEDTLS_PRIVATE(p_update)

Function that performs a cipher update operation.

psa_drv_se_cipher_finish_t
MBEDTLS_PRIVATE(p_finish)

Function that completes a cipher operation.

psa_drv_se_cipher_abort_t
MBEDTLS_PRIVATE(p_abort)

Function that aborts a cipher operation.

psa_drv_se_cipher_ecb_t
MBEDTLS_PRIVATE(p_ecb)

Function that performs ECB mode for a cipher operation (Danger: ECB mode should not be used directly by clients of the PSA Crypto Client API)
