WebIn this article, the authors analyze security and trust in NDN, to deduct the limits of the already proposed solutions. They propose a security extension that strengthens security and builds trust in used keys. The main idea of this extension is the derivation of these keys from data name, by using hierarchical identity-based cryptography HIBC.
