Security Support in Named Data Networking

This technical report presents an overview of the security support in the Named Data Networking (NDN) architecture that has been developed over the recent years. NDN changes the communication model from IP’s delivery of packets between hosts identified by IP addresses to the retrieval of named and secured data packets. Consequently NDN fundamentally changes the approach to securing communications. Making named data the centerpiece of the architecture leads to a new security framework which: (i) secures the data directly, and (ii) uses name semantics for applications to reason about security. In this paper we introduce NDN’s approach to security bootstrapping, data authentication, integrity, confidentiality, and availability. Note that this report is still in preliminary stage. We welcome all comments, and we plan to post an updated version in the near future.
