psa_drv_se_t struct
A structure containing pointers to all the entry points of a secure element driver. Future versions of this specification may add extra substructures at the end of this structure.
Syntax
typedef struct
{
uint32_t MBEDTLS_PRIVATE(hal_version);
size_t MBEDTLS_PRIVATE(persistent_data_size);
psa_drv_se_init_t MBEDTLS_PRIVATE(p_init);
const psa_drv_se_key_management_t *MBEDTLS_PRIVATE(key_management);
const psa_drv_se_mac_t *MBEDTLS_PRIVATE(mac);
const psa_drv_se_cipher_t *MBEDTLS_PRIVATE(cipher);
const psa_drv_se_aead_t *MBEDTLS_PRIVATE(aead);
const psa_drv_se_asymmetric_t *MBEDTLS_PRIVATE(asymmetric);
const psa_drv_se_key_derivation_t *MBEDTLS_PRIVATE(derivation);
} psa_drv_se_t;
Fields
Field
Declared as
Description
The version of the driver HAL that this driver implements. This is a protection against loading driver binaries built against a different version of this specification. Use #PSA_DRV_SE_HAL_VERSION.
The size of the driver's persistent data in bytes. This can be 0 if the driver does not need persistent data. See the documentation of psa_drv_se_context_t::persistent_data for more information about why and how a driver can use persistent data.
The driver initialization function. This function is called once during the initialization of the PSA Cryptography subsystem, before any other function of the driver is called. If this function returns a failure status, the driver will be unusable, at least until the next system reset. If this field is \c NULL, it is equivalent to a function that does nothing and returns #PSA_SUCCESS.

Function
Description
Return the secure element driver information for a lifetime value.
Register an external cryptoprocessor (secure element) driver. This function is only intended to be used by driver code, not by application code. In implementations with separation between the PSA cryptography module and applications, this function should only be available to callers that run in the same memory space as the cryptography module, and should not be exposed to applications running in a different memory space. This function may be called before psa_crypto_init(). It is implementation-defined whether this function may be called after psa_crypto_init().
