Abstract
In a single machine that has entities running in an untrusted environment and entities running in a trusted environment, the trustworthiness of the entities in the trusted environment is projected to the entities in the untrusted environment. This is applicable, for example, to Microsoft®'s Next Generation Secure Computing Base (NGSCB), where a regular operating system (e.g., the Windows® operating system) hosts a secure operating system (e.g., the nexus).
