Antigone: a flexible framework for secure group communication
Patrick Drew McDaniel, Atul Prakash, Peter Honeyman · Deep Blue (University of Michigan) · 1999
Many emerging applications on the Internet requiring group communication have varying security require-ments. Significant strides have been made in achieving strong semantics and security guarantees within group en-vironments. However, in existing solutions, the scope of available security policies is often limited. This pa-per presents the Antigone framework. Antigone provides a suite of mechanisms from which flexible application security policies may be implemented. Using this ap-proach, developers may chose a policy that best addresses their security and performance requirements. We describe the Antigone’s mechanisms, consisting of a set of micro-protocols, and show how different security policies can be implemented using those mechanisms. We also present a performance study illustrating the security/performance tradeoffs that can be made using Antigone. 1
