A Survivable Infrastructure for National Civilian Biodefense

    Overview

    The project focuses on developing the theoretical foundation and the protocols that facilitate a survivable information infrastructure that meets all the critical requirements of a national emergency response system. The proposed research will:
    • Develop the theoretical foundation and the protocols necessary to construct a large-scale survivable messaging system, resilient to the broad threat model, including insider attacks and denial of service, and man-in-the-middle attacks.
    • Develop the theoretical foundation and protocols to construct information access system that provides correct and authenticated data to users even in the presence of compromised database servers.
    • Develop the theoretical foundation and software that mitigate the effects of content providers injecting (authenticated and authorized but) incorrect content, either erroneously or maliciously. The developed capability will allow easy marking of corrupted or suspected data and will facilitate the return of the system to a correct state.

    Current research focuses on:

    • proposing architectures for anonymity systems with the consideration of scalability, robustness and quality-of-service, while preserving anonymity services.
    • design access control mechanisms for group oriented applications.
    • investigate the problem of dealing with malicious clients in data-driven applications.
