Dynamic adaptation to object state change in an information flow control model

Abstract

Dynamic adaptation to object state change is necessary for an information flow control model because object state may change in an unpredictable manner during runtime. To accomplish the adaptation, an information flow control model should offer the following features: (a) access rights can be dynamically changed according to object state change, (b) purpose-oriented method invocation can be achieved, and (c) information flows among variables can be controlled. According to our survey, no existing model offers the adaptation well. This paper proposes a solution to the adaptation, which is offered by the information flow control model object-oriented role-based access control.
