RNGs: A Super KISS /* For those mesmerized (or Mersenne-ized?) by a RNG with period 2^19937-1, I offer one here with period 54767*2^1337279---over 10^396564 times as long. It is one of my CMWC (Complimentary-Multiply-With-Carry) RNGs, and is suggested here as one of the components of a super-long-period KISS (Keep-It-Simple-Stupid)... 24 Nov 2009 11:08

Newton-Raphson division vs. Montgomery reduction According to <http://en.wikipedia.org/wiki/ Computational_complexity_of_mathematical_operations>, division, if implemented with Newton's method, has a complexity equal to that of whatever multiplication algorithm is in use. The article on Newton's method elaborates: "Newton–Raphson division ... can be used to quic... 26 Oct 2009 04:30
Rendering prediction of congruential random number generators hard [also posted to sci.crypt.random-numbers] Hi, Linear congruential generators were first broken by J. Boyar. She published an algorithm for inferring sequences produced by a linear congruential generator missing low-order bits. Later she also broke quadratic and cubic generators. Other researchers continued wo... 16 Oct 2009 18:32

Polyalphabetic substitution using two tables Hi, A recent post of mosherubin on the distinguished Chaocipher reminds me of the methodologies of classical crypto in general and as a consequence also of a conversation I had long time ago with a friend. We babbled one day over the application of polyalphabetic substituion ciphers and had as a topic in our cha... 2 Oct 2009 10:53

MBOL AAOT MBCL LUAT MKAT Hi there The worst that you can do is say "No - I won't help" I am hoping that you might. I am playing a game called geocaching - searching for a plastic box using a gps - no money involved - just the fun of finding the container and writing your name in it. Someone set a very difficult puzzle and encrypted ... 25 Sep 2009 07:34 |
