Function Documentation

◆ sl_cpc_security_get_state()

sl_cpc_security_state_t sl_cpc_security_get_state ( void )

Get the setup status of the security subsystem.

Returns
The setup status of the security subsystem.

◆ sl_cpc_security_fetch_user_specified_binding_key()

void sl_cpc_security_fetch_user_specified_binding_key ( uint8_t ** key,
uint16_t * key_size_in_bytes
)

User callback to provide CPC with a binding key.

SL_CPC_SECURITY_BINDING_KEY_METHOD config must be set to SL_CPC_SECURITY_BINDING_KEY_CUSTOMER_SPECIFIC

Parameters
[out] key The encryption key
[out] key_size The encryption key size Note: Only 16 bytes keys are supported for the moment

◆ sl_cpc_security_on_unbind_request()

uint64_t sl_cpc_security_on_unbind_request ( bool is_link_encrypted )

Authorize an unbind request.

Note
Declared as a weak symbol. If no strong definition is given by the user, unbind requests are always denied. If the user gives a definition for this function, its return value will dictate if unbind requests are accepted.
Returns
Whether to allow unbind or not, use SL_CPC_SECURITY_OK_TO_UNBIND as a return value to allow. Return anything else to deny.

◆ sl_cpc_security_unbind()

sl_status_t sl_cpc_security_unbind ( void )

Unbind device.

Returns
Status code.

◆ sl_cpc_security_unbind_subscribe()

sl_status_t sl_cpc_security_unbind_subscribe ( sl_cpc_unbind_notification_handle_t * handle,
sl_cpc_unbind_notification_t callback,
void * data
)

Register a callback that will be called when an unbind event occurs.

Parameters
[in] handle pointer to the unbind notification handle.
[in] callback pointer to the unbind notification callback.
[in] data pointer to pass to the unbind notification callback.
Returns
Status code.

◆ sl_cpc_security_unbind_unsubscribe()

sl_status_t sl_cpc_security_unbind_unsubscribe ( sl_cpc_unbind_notification_handle_t * handle )

Unregister a callback that will be called when an unbind event occurs.

Parameters
[in] handle pointer to the unbind notification handle.
Returns
Status code.
