Secure master server

German:
Man kann doch theoretisch auf jedem masterserver ein Spiel registrieren. Wie sicher ich meinen Master Server so das nur Server von meinem Spiel angemeldet werden dürfen?

English translation (Google translator):
You can theoretically register a Server on each master server without login or something like this. How can I protect my master server for misuse by other games.

Thanks

Come on no Ideas

What do you mean by protecting your master server from misuse from other games? I understand that when creating a master server you have a game name and that using a game name from other master servers could cause problems (I’m not sure what kind) but I think it can be avoided by using a unique name that no one would think of.

Thanks for answer.

I mean that every game can register a server at the master server. Is it possible to tell the master server to accept only one game name.

I may be wrong with this but I thought that the master server can only list one game name.

thanks
