摘要： Embodiments of apparatus, method, and storage medium associated with MCCG memory integrity for securing/protecting memory content/data of VM or enclave are described herein. In some embodiments, an apparatus may include one or more encryption engines to encrypt a unit of data to be stored in a memory in response to a write operation from a VM or an enclave of an application, prior to storing the unit of data into the memory in an encrypted form; wherein to encrypt the unit of data, the one or more encryption engines are to encrypt the unit of data using at least a key domain selector associated with the VM or enclave, and a tweak based on a color within a color group associated with the VM or enclave. Other embodiments may be described and/or claimed.
