Common Representation of Information Flows for Dynamic Coalitions

TL;DR

This paper introduces a formal framework called Common Representation for managing and reasoning about access control policies and information flow in dynamic coalitions, enabling better control of coalition evolution.

Contribution

It provides a novel abstraction over existing access control models, facilitating translation into an information-flow domain for dynamic coalition management.

Findings

Defines a formal foundation for access control in dynamic coalitions

Introduces the Common Representation model for information flow

Enables reasoning about coalition evolution with respect to information flow

Abstract

We propose a formal foundation for reasoning about access control policies within a Dynamic Coalition, defining an abstraction over existing access control models and providing mechanisms for translation of those models into information-flow domain. The abstracted information-flow domain model, called a Common Representation, can then be used for defining a way to control the evolution of Dynamic Coalitions with respect to information flow.
