Abstract

A method of creating a trusted execution domain includes initializing, by a processing device executing a trust domain resource manager (TDRM), a trust domain control structure (TDCS) and a trust domain protected memory (TDPM) associated with a trust domain (TD). The method further includes generating a one-time cryptographic key, assigning the one-time cryptographic key to an available host key id (HKID) in a multi-key total memory encryption (MK-TME) engine, and storing the HKID in the TDCS. The method further includes associating a logical processor to the TD, adding a memory page from an address space of the logical processor to the TDPM, and transferring execution control to the logical processor to execute the TD.
