ABSTRACT:
A computing platform20provides multiple computing environments24each containing a guest operating system25provided by a virtual machine application26.Optionally, each computing environment24is formed in a compartment220of a compartmented host operating system22. A trusted device213verifies that the host operating system22and each guest operating system25operates in a secure and trusted manner by forming integrity metrics which can be interrogated by a user10. Each computing environment is isolated and secure, and can be verified as trustworthy independent of any other computing environment.
