1) the upgrading platform inputs basic parameters of equipment needing to provide upgrading service;
2) the gateway equipment sends a boot message after being started, and the upgrading platform checks parameters and replies a boot message result after receiving the boot message;
3) the gateway judges the reply result, if the verification is passed, the periodic transmission ping message keeps connection, and the upgrading platform replies to the gateway ping message which passes the verification;
4) when the upgrading platform carries out upgrading operation on the gateway, firstly sending a check message, wherein the message carries the name and the version number of an auditing manufacturer, and after receiving the check message, the gateway checks the data and replies the check message result;
5) after the upgrading platform receives the verification result, if the verification fails, sending an end message; if the verification is successful, sending an upgrade message and carrying a download address of the security audit plug-in; after receiving the update file, the gateway downloads the update file according to the download address, starts updating, and replies an update message result after updating;
6) and after receiving the upgrading result, the platform sends an end message to indicate that the upgrading service is ended, and the gateway also replies the end message after receiving the message.
Further, in the above security upgrade method for a remote upgrade gateway security audit plug-in, in step 1), the security audit upgrade platform needs to enter basic parameters of a gateway that needs to provide an upgrade service, including a mac address, sn and supportable security audit manufacturer information, where the mac address is used to distinguish each gateway of the platform, and the sn is used to perform encryption verification when establishing a connection.

as shown in fig. 7, after receiving a check message sent by a platform, a gateway acquires a factor value to check whether the security and audit manufacturer is supported, if not, the check result is-1, and acquires a Version value to check whether the Version is higher than the current Version, if not, the check result is-2, if the checks are passed, the check result is 0, and then the gateway replies the platform check message, where the message is { "method": "check", "id": 145 "," result ": "0", the message contains a method value as check, and a result value as a check result value;
5) after the upgrading platform receives the verification result, if the verification fails, sending an end message; if the verification is successful, sending an upgrade message and carrying a download address of the security audit plug-in; after receiving the update file, the gateway downloads the update file according to the download address, starts updating, and replies an update message result after updating;
as shown in fig. 8, after the platform receives the check message replied by the gateway, if the result value is-1 or-2, it is determined that the verification fails, and the server sends an end message; if the obtained result value is 0, sending an upgrade message to the gateway, wherein the message is { "method": "upgrade", "id": 147 "," url ": "https:// omc1. itibia.com: 8000/anshen/loadfile/CMCC _ wifi w.tar' }, wherein the method value is upgrade, and the url value is the address of the download security audit upgrade file;
as shown in fig. 9, after receiving the upgrade message sent by the platform, the gateway acquires a url value, acquires a related upgrade file according to the url value, and upgrades the related upgrade file, and then the gateway sends the upgrade message, where the message includes a method value of upgrade, and if the upgrade is successful, a result value is 0, and the message is { "method": "upgrade", "id": 147 "," result ": 0, if the download of the upgrade file is abnormal, the result value is-1, if the upgrade file is abnormal, the result value is-2;
6) after receiving the upgrading result, the platform sends an end message to indicate that the upgrading service is ended, and the gateway also replies the end message after receiving the message;
step 3) after receiving the upgrade message sent by the gateway, the platform acquires a result value and synchronizes the upgrade state, and then sends an end message, as shown in fig. 10, the message is { "method": "end", "id": 148 "}, where the method value is end, and after receiving the end message, the gateway replies to the platform end message, as shown in fig. 11, the message format is {" method ": "end", "id": 148 "}, where the method value is end, which means the end of the upgrade.
