I taught this in my cryptography class last semester! I was shocked somebody tried to explain it in a single post, and did a great job!
And if you look at en.wikipedia.org/wiki/Developing_country Brazil is considered a newly industrialized country, so i guess it's above the stereotype of "third world"
Awesome explanation. I don't know about impossible cfw though. Surely there is another exploit somewhere that can bypass signatures like other consoles.
Also, as neat as ECDSA is to me, I feel like this is something easy for a math expert to come up with. Are there really that many systems that rely on the same model? I guess if it ain't broke...
Wow! What a math lesson that was reading. I took Calculus in college but man that's not for me!
i wonder if there is a way to "rip" a valid signature from a game, put that into a modified 4.0 so that no matter what is launched from the game category, that same valid signature gets used every time.
Ouchy, my head!
Very nice post though, might be one to revisit when the pain subsides
