Secure Information Sharing∗ A Final Report submitted to Network Information and Space Security Center (NISSC) for Spring 2004 Sponsored Project

The objective of the proposal is to examine the existing security models for supporting information sharing among multiple agencies and suggest extension for addressing the new requirement. Procedures for enforcing and tracking secure information distribution will be investigated. Existing group key management will be enhanced to address the scaling and tracking issues. To validate the revised security model and the secure information distribution procedures, a secure information distribution prototype based on SGFR secure instant messaging software we have developed in NISSC sponsored project will be developed. It will help identify the critical features and system design issues. Field trials with Northcom will be attempted in the follow-up project.
