Secure Socket + Client

I have a client and server program. It runs perfectly fine. I am worried about hackers. So far, I have placed all the restrictions and code on the clients. I now realize that if a hacker made his own program, he would be able to do some things that he shouldn't be able to do. What is the best way to create a secure socket + client?
One of the way I had previously thought of is to create a single, random 20 character string. When the server receives a message, it should check for that string. If it was a match, first takes off the first 20 characters, and then sends the message. If it wasn't, it doesn't. How secure is this system?

I assume you have implemented authentication (like username/password) and encryption already? That's where I would start.
