Isn't Marketing wonderful...
Here we are discussing which physical implementation is more secure,
and dear Dave tells us that Altera was indeed smart enough to implement
the algorithm correctly. I would never have stooped so low to doubt
that. Yes, Altera can do logic design. Bravo! Advance to second grade!

The question, however, was totally different: whether the key is
secure. And that is nowhere mentioned in that long URL.
Marketing 101:
If you have nothing good to say, throw in a big bunch of irrelevant
data.
That might defuse the argument. and calm down the waves...

Don't treat us like dummies.
