A method for solving a security problem in IP over ATM, the method comprising: accepting a connection request from an external second host, the first host in the LIS; If the second host sends an InATMARP-request message, and receives an InATMARP-obtaining an IP address of the first host by a reply message; The IP address of the first host acquired by the second host is transferred from the ATMARP server in the corresponding LIS to the ATMARP-request message, and the ATMARP server sends the ATMARP-obtaining an ATM address of the first host by a reply message, the ATMARP server searches whether the IP address of the first host and the ATM address are within the LIS, and if the IP address and ATM address of the first host are not in this LIS And disconnecting the connection, and initiating communication if it is present. Therefore, if you only have the server's security information in the LIS, and you need to keep the protocol and message format defined in RFC 1577 as it is, then you only need two more messages to solve security related problems.
