Abstract
Embodiments of copy equivalent protection using secure page flipping for software components within an execution environment are generally described herein. An embodiment includes the ability for a Virtual Machine Monitor (VMM), Operating System Monitor, or other underlying platform capability to restrict memory regions for access only by specifically authenticated, authorized and verified software components, even when part of an otherwise compromised operating system environment. In an embodiment, an embedded VM is allowed to directly manipulate page table mappings so that, even without running the VMM or obtaining VMXRoot privilege, the embedded VM can directly flip pages of memory into its direct/exclusive control and back. Other embodiments may be described and claimed.
