A struct containing all of the function pointers needed to for secure element key derivation and agreement.

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

If one of the functions is not implemented, it should be set to NULL.

Public Functions#

size_t
MBEDTLS_PRIVATE(context_size)

The driver-specific size of the key derivation context.

psa_drv_se_key_derivation_setup_t
MBEDTLS_PRIVATE(p_setup)

Function that performs a key derivation setup.

psa_drv_se_key_derivation_collateral_t
MBEDTLS_PRIVATE(p_collateral)

Function that sets key derivation collateral.

psa_drv_se_key_derivation_derive_t
MBEDTLS_PRIVATE(p_derive)

Function that performs a final key derivation step.

psa_drv_se_key_derivation_export_t
MBEDTLS_PRIVATE(p_export)

Function that performs a final key derivation or agreement and exports the key.
