Such hardware support may comprise a processor having a core, a hardware register to store a bit range to identify a number of bits, of physical memory addresses, that define key identifiers (IDs) and a partition key ID identifying a boundary between non-restricted and restricted key IDs. The core may allocate at least one of the non-restricted key IDs to a software program, such as a hypervisor. The core may further allocate a restricted key ID to a trust domain whose trust computing base does not comprise the software program. A memory controller coupled to the core may allocate a physical page of a memory to the trust domain, wherein data of the physical page of the memory is to be encrypted with an encryption key associated with the restricted key ID."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Co-existence of trust domain architecture with multi-key total memory encryption technology in servers","description":"Implementations described provide hardware support for the co-existence of restricted and non-restricted encryption keys on a computing system.
