Antigone: Implementing Policy in Secure Multiparty Communication

Significant strides have been made in achieving strong semantics and security guarantees within group communication and multicast systems. However, the scope of security guarantees available in existing frameworks is often limited. In contrast, applications increasingly require diverse security services in the face of changing environmental constraints.

This talk presents Antigone, a framework that provides a suite of mechanisms from which flexible application security policies can be implemented. A group security infrastructure is developed from the run-time composition and configuration of security mechanisms. Thus, using Antigone, developers may choose a policy that best addresses an application's immediate security and performance requirements. The design of the Antigone architecture is described, and several non-trivial policies illustrated. A number of design issues surrounding the construction of policy based security infrastructures are identified.
