Abstract
A method, apparatus, and system for storing memory encryption realm key IDs is disclosed. A method comprises accessing a memory ownership table with a physical address to determine a realm ID associated with the physical address, accessing a key ID association structure with the realm ID to determine a realm key IS associated with the realm ID, and initiating a memory transaction based on the realm key ID. Once retrieved, the realm key ID may be stored in a translation lookaside buffer.
