Poster: EMDns: Advancing Security and Privacy in Domain Name Resolution

Abstract

This paper presents EMDns, a domain name system based on Ethereum and MongoDB, addressing the centralization, security weaknesses, and privacy issues of the Domain Name System (DNS). EMDns enables automated and decentralized domain management to eliminate SPOF and authority dependence, while resolution is performed via local look-ups with hash comparison to protect privacy against deanonymization attacks. Experimental results show that EMDns maintains resolution efficiency while significantly enhancing security and privacy.
