The embodiment of the invention discloses an authentication method and device. In this method, the terminal sends a user's login request message to the server, and receives an authentication information sent by the server after determining that the user has successfully logged in; the terminal sends a SIP request message including the first authentication information to the IP-PBX, and receives the IP-PBX sending It can be seen that after the user logs in to the server, the server assigns the first authentication information to the user, and the user carries the first authentication information in the subsequent SIP request message, and the IP-PBX authenticates the first authentication information. Since the illegal user cannot successfully log in to the server to obtain the first authentication information, after receiving the SIP request message sent by the illegal user, the IP‑PBX will reject the SIP request of the illegal user due to the failure of the first authentication information authentication, thus effectively rejecting the SIP request. Mitigate and avoid the risk of piracy, and protect expensive long-distance telecommunications resources.

The present invention provides an on-site busbar protection method and system based on a star network topology. A network of on-site distributed busbar protection devices is constructed through a star network topology, and any one of the on-site distributed busbar protection devices The busbar protection device acts as the protection master, and other devices act as slaves.
