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.enICNNDNtrustDDC::000 Informatik, Informationswissenschaft, allgemeine Werke::000 Informatik, Wissen, Systeme::004 Datenverarbeitung; Informatikconference paper
