  • KaKaRoTo Speaks of ECDSA Algorithm - CFW Impossible

    I have always wanted an explanation of the ECDSA algorithm due to it's mathematical complexity. Anyone who knows anything about PS3 encryption and the hidden keys used to calculate the ECDSA know that it isn't an easy feat. PlayStation 3 developer KaKaRoTo has tried to simplify the subject for us in order to gain some knowledge on the subject. Below is an extract, you can read the full article linked at the source below.


    To Quote:
    To popular demand, I have decided to try and explain how the ECDSA algorithm works. I’ve been struggling a bit to understand it properly and while I found a lot of documentation about it, I haven’t really found any “ECDSA for newbies” anywhere. So I thought it would be good to explain in simple terms how it works so others can learn from my research. I have found some websites that explain the basic principles but nowhere near enough to actually understand it, others that explains things without any basics, making it incomprehensible, and others that go way too deep into the the mathematics behind it.
    Please continue to read the bottom of his article if you are feeling to lazy to read.

      And yet, you're wrong. Sorry, but some things really are impossible, and cannot ever be done, even given an infinite amount of time.

      Nothing is really impossible, you know (regarding cryptography and console security, that is). If you are simply talking about brute-force attacks, then yes, most of security features existent nowadays (one time pads, ECDSA, etc) are uncrackable. However there will still exist other methods to break those security layers, mainly because no implementation can be perfect.

      I'm not sure why "anything" would refer to game console security.
