Securing Domain Name System Using Advanced Encryption Standard

Abstract

The mapping of IP addresses to host names is a major problem in rapidly growing internet. The higher level binding effort went on increasing to different level of development up to the currently used Domain Name System. DNS, being an open source, it is less secured and it has no means of determining whether domain name data come from an authorized domain owner. So these vulnerabilities lead to a number of attacks. Hence, there is a need of securing DNS. This paper approaches the Advanced Encryption Standards that uses symmetric key concepts. Domain Name System has number of workgroups and these workgroups are connected to the server. This server is connected to the server of other domain and the proposed system secures client that is attacked, using AES.
