The following paper describes a security scheme for a distributed multimedia environment called Switchboard. After a brief introduction to the philosophy of the Switchboard and the underlying system model, the main building blocks of the concept are described. These are: an authentication mechanism preventing intruder attacks and a protection scheme based on an extended access control matrix approach. This protection scheme covers both static and dynamic aspects of access protection for multimedia devices. Some remarks on the implementation of the mechanisms and a discussion conclude this paper.
