Abstract:
Embodiment of this disclosure provide techniques to support full memory paging between different trust domains (TDs) in compute system without losing any of the security properties, such as tamper resistant/detection and confidentiality, on a per TD basis. In one embodiment, a processing device including a memory controller and a memory paging circuit operatively coupled to the memory controller is provided. The memory paging circuit is to evict a memory page associated with a trust domain (TD) executed by the processing device. A binding of the memory page to a first memory location of the TD is removed. A transportable page that includes encrypted contents of the memory page is created. Thereupon, the memory page is provided to a second memory location.
