Abstract

We show how to create a master key scheme for controlling access to a set of services. Each master key is a concise representation for a list of service keys, such that only service keys in this list can be computed easily from the master key. Our scheme is more flexible than others, permitting hierarchical organization and expansion of the set of services.
