Description

Privacy preservation on DNS-based name resolution has become one of the important issues in the Internet. DNS over TLS (DoT) and DNS over HTTPS (DoH) which have been standardized by the IETF, can prevent falsification of the DNS traffic and direct leakage in the communication link. However, the DNS traffic encryption cannot hide the source and destination IP addresses from which the queried domain name can be speculated. Therefore, in this paper, we propose a novel DoH-based name resolution architecture to prevent the risk of domain name speculation from the IP header of DNS packet. According to preliminary evaluations, we confirmed that the DNS traffic between end clients and DNS authoritative servers can keep the anonymity and the risk of queried domain name speculation can be significantly mitigated
