Abstract

본 발명은 IP over ATM에 있어서 보안문제 해결방법에 관한 것으로서, LIS 내부의 제1호스트가 외부의 제2호스트로부터 연결 요구를 수락하는 단계; 제2호스트가 제1호스트에게 InATMARP-request 메시지를 보내고, 제1호스트로부터 수신되는 InATMARP-reply 메세지에 의해 제1호스트의 IP 어드레스를 획득하는 단계; 제2호스트가 획득한 제1호스트의 IP 어드레스를 해당하는 LIS 내부의 ATMARP 서버에서 ATMARP-request 메세지에 실어 보내고, ATMARP 서버로부터 ATMARP-reply 메세지에 의해 제1호스트의 ATM 어드레스를 얻는 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, LIS내의 보안에 관한 정보를 서버만 가지고 있도록 하고, RFC1577에 정의된 프로토콜과 메세지 포맷을 그대로 유지하면서 메세지 2개만을 더 소요하면 보안에 관련된 문제를 간단히 해결할 수 있다.The present invention relates to a security problem solving method for IP over ATM, comprising: accepting a connection request from an external second host by a first host in an LIS; Sending, by the second host, an InATMARP - request message to the first host, and obtaining an IP address of the first host by means of an InATMARP - reply message received from the first host; Sending the IP address of the first host obtained by the second host to an ATMARP - request message in an ATMARP server in a corresponding LIS, and obtaining an ATM address of the first host by an ATMARP - reply message from the ATMARP server; Search for whether the IP address and ATM address of the first host are in this LIS, and disconnect if the IP address and ATM address of the first host are not in this LIS. . Therefore, if only the server has security information in the LIS and maintains the protocol and message format defined in RFC1577, only two more messages can be solved.
