Abstract

If signalling channels can only be driven by the Trusted Path, they cannot be exploited by Trojan Horses in untrusted software. To this end, the SMITE system aims to provide a general purpose Trusted path, based on a screen editor, which would act as the users' normal interface to the system. The feasability of the approach relies on the use of a sympathetic computer architecture, which supports a fine grain of protection.
