Abstract
Various embodiments described herein relate to apparatus for executing software in a secure computing environment. A secure processor can be used and configured to request a context swap from a first context to a second context when switching execution from a first portion of software to a second portion of software. A context manager, which can be in communication with the secure processor, can be configured to receive and initiate a requested context swap. A trust vector verifier, which can be in communication with the secure processor and the context manager, can be configured to load a trust vector descriptor upon command from a context manager.
