Abstract:
A computing platform 20 provides multiple computing environments 24 each containing a guest operating system 25 provided by a virtual machine application 26. Optionally, each computing environment 24 is formed in a compartment 220 of a compartmented host operating system 22. A trusted device 213 verifies that the host operating system 22 and each guest operating system 25 operates in a secure and trusted manner by forming integrity metrics which can be interrogated by a user 10. Each computing environment is isolated and secure, and can be verified as trustworthy independent of any other computing environment.
