Abstract
Implementations for providing a persistent secure execution environment with a hosted computer are described. A host operating system of a computing system provides an encrypted checkpoint to a persistence module that executes in a secure execution environment of a hardware-protected memory area initialized by a security-enabled processor. The encrypted checkpoint is derived at least partly from another secure execution environment that is cryptographically certifiable as including another hardware-protected memory area established in an activation state to refrain from executing software not trusted by the client system.
