Content Security over ICN based Smart Grid: A Cryptographic Solution

Information-Centric Networking (ICN) has been widely regarded as a new, promising networking paradigm for smart grids. Accordingly, content security becomes the most critical security goal, because the content is now decoupled from its location in ICN. As existing security approaches are mainly designed for traditional IP-based smart grids, how to achieve content security in ICN-based smart grid remains unexplored. In this work, we first propose a two-layer ICN architecture to move from host-centric communication to receiver-driven data retrieval. Then, we design a pseudo-identity signcryption scheme based on receiver-driven communication patterns to achieve mutual authentication and various other security goals, assuring content security in an ICN-based smart grid. Experiments and comparison results show the superiority of our proposed scheme.
