The invention discloses multi-key cryptographic memory protection. In one embodiment, an apparatus comprises a processor to execute instruction(s), wherein the instructions comprise a memory access operation associated with a memory location of a memory. The apparatus further comprises a memory encryption controller to: identify the memory access operation; determine that the memory location is associated with a protected domain, wherein the protected domain is associated with a protected memory region of the memory, and wherein the protected domain is identified from a plurality of protecteddomains associated with a plurality of protected memory regions of the memory; identify an encryption key associated with the protected domain; perform a cryptography operation on data associated withthe memory access operation, wherein the cryptography operation is performed based on the encryption key associated with the protected domain; and return a result of the cryptography operation, wherein the result is to be used for the memory access operation.
