A MAS FOR ACCESS CONTROL MANAGEMENT IN COOPERATIVE INFORMATION SYSTEMS

International audienceThis proposition deals with interoperation of data and security policies in cooperative information systems. We use the agent paradigm for the treatment of distributed programs and perform complex tasks through cooperation and interactions. A combination of two methods - GAIA and AUML- and a set of models are used. Two protocols are defined related to the features of the system: (i) a knowledge management protocol to address interoperability problems between different modes of data representation and security access models and, to generate the matches between these models, (ii) a query resolution protocol using global knowledge. Agents are described in their goals, their interactions, their knowledge by defining their roles for each protocol, including the key role of the security mediator. A prototype is implemented on the JADE platform (Java Agent Development Environment
