Deborah L. Estrin, Gene Tsudik · 1987
In this paper we describe a visa scheme for implementing access control in Inter-Organization Network (ION) gateways. The purpose of the scheme is to allow an organization to modify and trust only them internal system that require ION access all other internal system can not communicate with the outside. Control is distributed among the ION participants so that each may make its own design tradeoffs between performance and trust.
