Implementation and evaluation of encrypted communications between DNS clients and servers

Synopsis Domain Name System (DNS) is a network database which relates a host name to corresponding administrative information such as an IP address or a mail exchanger's location. Since DNS data had considered public for long years, no efforts for hiding the data have made. However, bad attempts using DNS data have emerged. While some developments to protect. DNS data on the DNS server have progressed, there is still no action aagainst .one dal a theft, via wire tapping. In this paper, we propose some alternatives t.o achieve secure communications between DNS clients and servers. We also show that prototype architecture of
