At ubiquitous environment DNS, it is essential IT infra was acquired increasingly importance. At same time, vulnerable attack about DNS has increased. So, security of DNS is extension to DNSSEC. as a result that has guaranteed data integrity between DNS server and client by using public key of DNSSEC. but, communication between DNS severs used symmetric key. Most vulnerability at the communication between DNS servers doesn't exist certification or was able to dictionary attack because DNS security has used long term key. We make a proposal mechanism that used authentication key pool and public key of DNSSEC. the one work powerful authentication and then key establishment effectively. For safety check, we analyzed the mechanism safety by using BAN logic. In result, poroposal mechanism was proved to be sefety. And proposal mechanism performance of key generation and encryption and decryption has markedly improved as compared with Diffie-Hellman mecahnism. And proposal mechanism performance of communication has improved as compared with Kerberos V5.
