Plain-text communication of DNS queries poses a risk of privacy leakage. Therefore, it is imperative to achieve protection through encryption for DNS communication between end terminals and full-service resolvers, as well as between full-service resolvers and authoritative DNS servers. The IETF has published an internet-draft for encrypting communication between full-service resolvers and authoritative DNS servers. However, this approach prioritizes compatibility with existing plain-text communication, which means that the risk of privacy leakage remains until a full-service resolver discovers an authoritative DNS server compatible with encrypted communication. In this paper, we propose a method to achieve the compatibility and privacy protection by adding dummy NS records indicating the status of support for encrypted communication of respective zones to the authoritative DNS servers of each zone. Additionally, we discuss the implementation and functional verification of this proposed method. |
