SoK: Public key and namespace management in NDN

Named data networking (NDN) enables scenarios where decentralized content distribution based on names is the centerpiece of networking. In this paper, we systematize two requirements to enable trust on a global scale in NDN, namespace management and public key management. We provide a framework to systematically assess and evaluate namespace and public key management systems, and relate their features to DNSSEC and Web PKI, the most prominent and accessible implementations of both building blocks on the current Internet. Our systematization of knowledge of existing approaches in NDN highlights strengths and shortcomings to derive options for future research.
