The possibility of a massive, networked infrastructure of diverse
entities partaking in collaborative applications with each other increases
more and more with the proliferation of mobile devices and the
development of ad hoc networking technologies. In this context, traditional
security measures do not scale well. We aim to develop trust-based
security mechanisms using small world concepts to optimise formation
and propagation of trust amongst entities in these vast networks. In this
regard, we surmise that in a very large mobile ad hoc network, trust, risk,
and recommendations can be propagated through relatively short paths
connecting entities. Our work describes the design of trust-formation and
risk-assessment systems, as well as that of an entity recognition scheme,
within the context of the small world network topology.
