But doesn't the UDP header include the sender IP address? So
together with the magic number, shouldn't it be good enough? I
know it definitely is not going to hold against jamming or a man
in the middle, but it isn't supposed to, at this stage. It's used
only for simulations that have the criticality of a casual Tetris
I do acknowledge that the needs may rise later on. And if so, I
understand that I'm much better off switching the protocol than
trying to hardening the UDP.
