Capabilities for Distributed Authorization in Information-Centric Networking

Abstract: Authorization currently introduces partial centralization in otherwise distributed network architectures, such as ICN approaches. Analyzing existing work in (partially) distributed authentication and authorization, and rearranging proven methods, this paper introduces a generalized, capability based and fully distributed authorization scheme. It argues that such a scheme can fit neatly into ICN architectures in order to enhance the trust model and mitigate against certain classes of denial-of-service attacks.
