Device fingerprint for secure client access over tls network

We want to create a unique machine id - key fingerprint, in order to use it to identify a PC(s) over a secure network (probably ssl/tls), so that we are sure that the server delivers to the certain PC , and not to someone who has stolen the license. The pc(s) will be on Linux OS. 开发者_如何学编程How should we do it?

Couple of suggestions.

1. Create a unique hashing algorithm that hashes the computer name and MAC address together, sends the hash back to the secure server, and stores it in a binary file on the local machine. When communicating, your protocol then requires the client to send it's hashcode fingerprint to the server to authenticate before communicating.

2. Generate a set of valid license keys (another hash) that you store in a special file. When the application boots for the first time, it registers the key and computer information with the server (ie: computer name) or username/password combo. As with #1, the computer must send the unique key to the server to authenticate before communicating. Set up your server code so the same key cannot come from two different devices.
