Abstract

In the secure DNS the amount of information that should be managed greatly increased and the interdependency in the information became very complex. Therefore, it became necessary to develop a mechanism which can manage zone information efficiently. Moreover, a consistent interface became also necessary so that a secure DNS may be efficiently interconnected with other Internet application services. In this paper we explain the design and implementation of a secure DNS extended with two functions(1) a dynamic update function which enables to add and remove zone information dynamically and (2) a zone transfer function that efficiently transfers updated zone information among DNS servers. We developed a method which integrates two zone transfer mechanisms, full zone transfer and incremental zone transfer, and also proposed a method to compress data in the zone transfer message. We also introduced a data structure called a delta file to integrate the zone transfer function and the dynamic update function.
