ABSTRACT:
Each software component loaded for a verified operating system on a client computer must satisfy a set of boot rules for a boot certificate. A verified operating system identifier is created from the boot certificate. The boot certificate is published and signed by a boot authority that attests to the validity of the operating system booted under the boot certificate. Each software component for the operating system is associated with a component certificate published and signed by the same boot authority that signed the boot certificate. The boot rules determine the validity of the software component based on the contents of the component and boot certificates. The client computer can transmit the verified operating system identity and the boot certificate to a server computer, such as a content provider, and the content provider can determine whether to trust the verified operating system with its content.
