Abstract

The Monash Multiprocessor Architecture incorporates a monetary system at the lowest kernel level, integrated with a password capability scheme. Although the capability scheme is quite flexible, providing support for non-hierarchic security and access policies, abstract type management and information confinement, we show that it is possible for service providers to command use-based fees for service. The fee charging protocols must be designed with some care to avoid breaching required information confinement constraints when user and provider are mutually suspicious, but need not be very complicated.
