Securing Domain Name Systems with Blockchain
Joshua Theoder, Binusha Shabu Metharath, Sahel Alouneh · 2023
This paper discusses the limitations of the hierarchical and centralized Domain Name System (DNS) and the challenges it poses to net-neutrality and privacy. Despite the use of digital signatures based on public key cryptography, DNS attacks continue to affect data integrity, confidentiality, and service availability. The paper argues for the exploration of emerging technologies, such as blockchain, to promote data encryption and authentication through a decentralized and non-hierarchical approach. The project aims to research and develop novel DNS name-resolution techniques using blockchain technology and to explore their potential benefits and limitations.
