A struct containing all of the function pointers needed to perform secure element MAC operations.

PSA Crypto API implementations should populate the table as appropriate upon startup.

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

Driver implementers should ensure that they implement all of the functions that make sense for their hardware, and that they provide a full solution (for example, if they support p_setup, they should also support p_update and at least one of p_finish or p_finish_verify).

Public Functions#

size_t
MBEDTLS_PRIVATE(context_size)

psa_drv_se_mac_abort_t
MBEDTLS_PRIVATE(p_abort)

Function that aborts a previously started MAC operation.

psa_drv_se_mac_generate_t
MBEDTLS_PRIVATE(p_mac)

Function that performs a MAC operation in one call.
