Abstract
Implementations for providing a secure execution environment with a hosted computer are described. A security-enabled processor establishes a hardware-protected memory area with an activation state that executes only software identified by a client system. The hardware-protected memory area is inaccessible by code that executes outside the hardware-protected memory area. A certification is transmitted to the client system to indicate that the secure execution environment is established, in its activation state, with only the software identified by the request.
