Antigone is the main character in a play of the same name by Sophocles written in 441 B.C. A central theme of the play is the investigation of the fundamental nature of conflict. The Antigone framework attempts to manage the conflicting requirements for group semantics, security, and performance.
The Antigone project has developed a policy framework for secure group communication. The Antigone 2.0 framework provides interfaces for the definition, evaluation, distribution, and enforcement of secure group policies.
The Antigone system is a middleware layer that provides flexible interfaces for defining policy in group applications. Central to the design of Antigone is the definition of a suite of mechanisms that provide the core secure group services. Through the composition of the Antigone mechanisms (and their underlying micro-protocols), an application may precisely define the group policy. The component design achieves technology and infrastructure independence; new mechanisms may integrate desired functionality without affecting other system services. Our initial implementation of Antigone demonstrates the viability of this approach by providing template policies representing those available in the vast majority of existing systems. Currently, we are working to identify the design space of group policies and a range mechanisms needed to implement them. Furthermore, we are addressing performance, fault tolerance, and reliability issues within Antigone through the integration of existing and emerging technologies.
