A Novel Framework for Security Enforcement in Networks for Disaster and Crisis Management

The paper proposes a framework that provides security in networks deployed in disaster areas. Traditional networks are not well suitable to use in such setting due to many unusual constraints such as long delays, high packet drop rates, unavailability of central trusted entity etc. Under such constraints existing security protocols do not work. Proposed here approach provides solutions for some of these problems often listed as challenges in the literature. We consider delay-tolerant wireless networks as a most suitable for such setting, and propose a trust based approach that provides flexible and efficient solutions that can be used in disaster arears.
