초록

최근 무선 통신장치들이 매우 빠르게 발전되고 사용자에게 보급되고 있다. 이로 인해서 기존의 유선 네트워크 장치들과 새로운 무선 네트워크 장치들을 통합한 새로운 메쉬 네트워크에 대한 요구가 급속히 발전하고 있다. 이런 유 무선 통합 네트워크 환경에서 자동으로 네트워크를 구성하고, 이런 환경에서 사용자 또는 유 무선 통신장치에 대해 인증서비스를 반드시 제공해야만 한다. 하지만 현실적으로 이런 서비스를 제공하고 있지 못하다. 그러므로 본 논문에서 유 무선 통합 네트워크 환경에서 오픈플로우를 사용해 네트워크를 자동으로 구성하고, 커베로스를 응용한 사용자 인증시스템을 제안하였다. 우리가 제안한 인증시스템은 장치 또는 사용자에 대한 인증서비스를 제공할 수 있을 뿐만 아니라, 비밀성, 무결성 서비스를 제공할 수 있다. 추가로 중간자공격에 대해서도 막을 수 있다.

Recent, development of wireless communication devices are rapidly and these device being deployed to the user very fast. By this results, a wired network device and the new device such as wireless devices incorporate. Then a demand of new mesh network is rapidly growing. In this wired/wireless integrated network environment, the network is configured automatically, and a user or wireless communication devices must be provided for authentication services. But, these services do not in the real world. Therefore, in this paper, we propose that wired/wireless integrated network environment to automatically configure the network using OpenFlow and the authentication system using Kerberos method. Our proposed system to be able to provide authentication services, confidentiality, integrity services for user or wired/wireless communication devices. And it can be prvented as well to man-in-the-middle attacks.
