Abstract

In recent years, Named Data Networks (NDN) have been proposed as a promising paradigm for the Internet of the future because of their disruptive content-centric feature. In order to ensure content authenticity, NDN relies on the use of digital signature which, due to the complexity involved in the validation process, may result in additional processing overhead. As a result, NDN implementations are susceptible to a variety of attacks. This work proposes a security framework that aims to use blockchain technology attributes to enable verification of the integrity and authenticity of NDN content. Results obtained from emulation showed that the proposed framework can detect data tampering attacks and prevent the misrepresentation of content by malicious providers.
