> You keep saying "the Galois Field" as if that was a thing
You're kidding, right? You've never looked at how GCM-mode works? The entire set of math is inside of the GF(2^128) field. That's why its called a Galois Counter Mode.
I don't think anyone should be implementing their own GCM mode. Its very subtle and potentially full of traps. CBC on the other hand is pretty dumb and simple, and surprisingly secure and robust
> Vulnerabilities in CBC systems were for a long time during the 2000s the most common crypto vulnerabilities on the Internet. There are more things that go wrong with CBC mode than just forgetting to authenticate it!
If they're so common, you shouldn't have much of an issue naming one such vulnerability.
