PROJECTION OF TRUSTWORTHINESS FROM A TRUSTED ENVIRONMENT TO AN UNTRUSTED ENVIRONMENT

摘要

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 TM 's Next Generation Secure Computing Base (NGSCB), where a regular operating system (e.g., the Windows TM operating system) hosts a secure operating system (e.g., the nexus).
