Description
Summary:	DNS over Transport Layer Security (DoT) has been standardized in the Domain Name System (DNS) to protect the confidentiality of communications between stub resolvers and recursive resolvers. In addition, the standardization for introducing encrypted communication between recursive resolvers and authoritative servers is in progress in IETF. In this paper, we assume that authoritative servers have X.509 certificates to support DoT and propose a mechanism that enables users to determine whether or not a domain name that is similar to or closely associated with a legitimate domain name (possibly a "cousin domain") is actually associated with it.
