title: Unity 3D secure authentication with SQL
body: <p>I'm developing an android application in unity 3d that will have network communications for user accounts updating said accounts as well as controlling everything on the back end of the app. I use the WWW class in unity to send info to the server. The backend is php and all the data is stored in a mysql database. How can I make a secure connection between the app and the backend without someone just simply getting the servers address and blocking it in their hosts file and feeding the app false info and going online with it.(as an example) I'm no security expert but I'm not sure what I need to look in too in order to create secure connections between server and client. Any help would be greatly apericiated. Thank you.</p>
