RE: Theory of Relative Squares - AJMansfield - 02-14-2014 If you could find a really efficient way to calculate given for some , there is a way to use that to crack an RSA encryption.

RE: Theory of Relative Squares - AJMansfield - 02-14-2014 What I mean, is that if all you knew was , normally you have to take its square root (a tedious, process, where the current best for ) to find , and then you can just do to get . But if you could figure out how to get from without needing to calculate , you could crack RSA using the difference-of-squares method much more quickly than existing methods. Basically, find a way of computing a square root of a perfect square that is significantly faster than multiplying two numbers of the same lemgth, and you win. (Not that I expect this to ever happen.) RE: Theory of Relative Squares - Iceglade - 02-15-2014 Yeah, I'm not sure how that would be done if it was at all. It would be an interesting thing to look into at some point though, I guess. RE: Theory of Relative Squares - Dcentrics - 02-21-2014 * Dcentrics stares in disbelief RE: Theory of Relative Squares - CrazyPyroEagle - 06-08-2016 (a + b)^2 - a^2 = a^2 + 2ab + b^2 - a^2 = b^2 + 2ab It's not as simple in different powers though. (a + b)^3 - a^3 = a^3 + 3ba^2 + 3ab^2 + b^3 - a^3 = 3ba^2 + 3ab^2 + b^3 RE: Theory of Relative Squares - Chibill - 06-08-2016 Please don't bump threads older than a year. RE: Theory of Relative Squares - LordDecapo - 08-13-2016 It was bumped already... But I'll add this here N^2 = (N-1)^2 + (N-1) + N |
