Abstract

본 발명은 IP over ATM 교환기에 있어서 보안문제 해결방법에 관한 것으로서, LIS 내부의 제1호스트가 외부의 제2호스트로부터 연결 요구를 수락하는 단계, 제2호스트가 InATMARP-request 메시지를 제2호스트가 위치한 LIS내의 ATMARP 서버로 전송하는 단계, InATMARP-request 메세지를 받은 ATMARP 서버가 목표 ATM 어드레스 필드에 해당하는 IP 어드레스를 발신하는 단계, ATMARP 서버가 제1호스트의 IP 어드레스와 ATM 어드레스가 이 LIS내에 있는가에 대하여 검색하여, 제1호스트의 IP 어드레스와 ATM 어드레스가 이 LIS내에 없는 경우 연결을 해제시키고, 있는 경우 통신을 개시하는 단계로 구성된다. 따라서, 교환되는 메세지 수를 2개로 유지하면서 기존의 RFC1577을 사용하는 호스트와 프로토콜 호환이 되는 동시에 보안에 관련된 정보를 서버에게 집중시킬 수 있다.The present invention relates to a method for solving a security problem in an IP over ATM switch, wherein a first host in an LIS accepts a connection request from an external second host, and the second host sends an InATMARP - request message to the second host. Transmitting to the ATMARP server in the LIS located; sending the IP address corresponding to the target ATM address field by the ATMARP server receiving the InATMARP - request message; Search for and release the connection if the IP address and ATM address of the first host are not in this LIS, and initiate communication if present. Therefore, while maintaining the number of messages exchanged at two, it is possible to concentrate the security-related information on the server while being protocol compatible with the host using the existing RFC1577.
