    abstract     = "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."
