초록

A message server have two basic functionalities, a server role for processing the processing the user environment as well as an entity role for transferring message to other entity in message system environment. The user who is going to send and receive his important information really wants to keep his own security requests. To satisfy this requirement, message server must be enforced by two seperated security policies- one for message processing security policy under department's computer working environment, the other for send/receive security policy under message system's communication path environment. Proposed access control model gurantees the user's security request by combining constrained server access control and message system access control with multi upper bound properties which come from inheritance attributes of originating user security contexts.
