We use this architecture as foundation for an implementation in our agent system MASA (Mobile Agent System Architecture). Several existing security technologies are considered for the suitability in agent systems, e.g. for confidentiality and integrity. We commenced to implement first parts like authentication. Evaluation of different concepts to model rights will follow soon. Afterwards, components depending on rights can be implemented. An authorization component must go along with access and resource control mechanisms. After completing these basic components for rights, delegation and non-repudiaton need closer attention.
Development of configuration and policy management of this security architecture should accompany all this although it needs some more considerations about management of mobile agent systems in general before.
