Trustworthy Information: Concepts and Mechanisms

We used to treating information received (from recognized sources) as trustworthy, which is unfortunately not true because of attacks. The situation can get worse with the emerging shift of information sharing paradigm from “need to know” to “need to share.” In order to help information consumers make the “best” decision possible, it is imperative to formulate concepts, models, frameworks, architectures, and mechanisms to facilitate information trustworthiness management in distributed and decentralized environment. In this paper we initiate a this direction by proposing an abstraction called information networks as well as two supporting mechanisms called provenance digital signatures and optimal security hardening of information network.
