End-to-end encrypted scalable abstract data types over ICN

Abstract

In Information Centric Networking (ICN), data items are made accessible through their name rather than their storage location. We extend this storage abstraction and complement it via a name lookup service for retrieving the latest version of a name binding in order to implement abstract data types (ADT), specifically “append-only logs” and “mutable key-value stores”. Moreover, we make these data types scalable by choosing implementation techniques known as CRDTs (conflict-free replicated data types) and we use end-to-end encryption for protecting the content and structure against untrusted storage providers and forwarding elements. In this paper we describe our architecture, the interface to the ADTs and report on a prototype implementation for the cloud that is inspired by a real Fintech use case.
