Providing Survivable Real-Time Communication Service for Distributed Mission Critical Systems

Abstract : This document is the final report for Providing Survivable Real-Time Communication Service for Distributed Mission Critical Systems, a Texas A&M project funded through the DARPA Fault Tolerant Networks Program. In this project, we have developed techniques for survivable real-time services for mission critical systems. In particular, we incorporated real-time traffic modeling techniques into the security service to enhance both system security and real-time capabilities in an adverse environment. This is the key element that has made our work innovative and unique. We utilized a combination of traffic stuffing based on traffic-modeling and intrusion detection/monitoring as highly effective countermeasures against both traffic analysis and denial of service forms of attack in both wired and wireless networks. The threat of traffic analysis is particularly critical in wireless environments, where the operational mode of the critical applications can be easily inferred. The project has been successful. We developed a system called NetCamo which integrated the technologies we developed into a deployable form. NetCamo was successfully integrated into the Navy's Hi-Per-D system. Further, NetCamo was transferred to an industrial company for deployment in both DoD and commercial domains.
