I have a tcp server at Google cloud platform. This talks to my clients under a dynamic encryption key that will change after each time they talk.
The only thing that happens between the server and the client is that:
- client sends its data from its 'license' key
- and the server just replies with a new license key
- then the connection stops
What are the things I have to watch out for? Can hackers steal data from my client outside of the encryption license key?
