Abstract
An example computer-implemented method includes presenting, by a hardware control of a computing system, an exception to an untrusted entity when the untrusted entity accesses a secure page stored in a memory of the computing system, the exception preventing the untrusted entity from accessing the secure page. The method further includes, in response to the exception, issuing, by the untrusted entity, an export call routine. The method further includes executing, by a secure interface control of the computing system, the export call routine.
