  Who Will I Choose?         


Author: apollo66942

I'm still feeling light-headed about my dream last night. I cannot
believe it. After waiting for a peaceful sleep for the past couple of
weeks and actually enjoying it, I faced a very scary dilemma. I had a
dream, no, no, it's a nightmare. And I'm dreading to sleep later
because until now I don't have the answer to the terrifying question.

I was practically enjoying the calm feeling of my sleep when out
nowhere I was standing in the middle of a very very big arena. I was
distressed and confused by the sudden change of surroundings. I was
starting to be afraid when I heard a thundering sound coming from my
back. Ready to shout with all my might, I turned around and my jaw
dropped not because of my scream but because of an outmost amazement.

My king, the love of my life, was riding his horse,Brego, and stopped
infront of me. Oh, my Aragorn, I cannot believe it. I was about to
finally let a scream of delight pass through me when he grabbed my
hand and offered the most outrageuos proposal I've heard in my whole
life. He wanted me to be his queen. At long last, he said, Arwen was
out of his life and he came to me because I am the only one his heart
desires. Ohhh, what can I say? How can a lady like me answer an offer
like that?

That's why N has to be odd, but also note then that 'a' needs to be
coprime to N, so if you get an 'a' that is not, then it's not a useful
value.

  modulo arithmetic V xor         


Author: Antony Clements
Date: Jan 26, 2008 23:23

I have been doing some reading on using modulo arithmetic as opposed to
using the xor function, i know that the xor function is modulo 2 arithmetic,
the question is, would breaking the xor function down into N steps decrease
the memory footprint of an algorithm, if so the reduction in time should
vary depending on the size of input 1 and input 2 and how many of them there
are, as part of a stream cipher for example.

the further question arises of how to break it down into steps, i know how
to break down modulo exponentiation but not any of the other forms of modulo
arithmetic.

links to reference material or explenations would be most welcome.

  What's up with Skype in Germany?         


Author: Peter Pearson
Date: Jan 26, 2008 22:03

Would any German-speaking sci.crypt participant be so obliging
as to visit
http://wikileaks.org/wiki/Skype_and_the_Bavarian_trojan_in_the_middle
and describe the leaked memo? The phrase "trojan in the middle"
seems confused. I wouldn't expect Skype to be vulnerable
to a man-in-the-middle attack. Does this attack depend on
infecting the victim's computer with malware?

so we gotta picka "m",
picka "N",
and picka "y" or picka "z".
> z = (2a)^{-1}(1 + 2a^2)k mod N

Now we gotta picka "k"
and picka "a"

We are up to guessing 5, *FIVE* numbers, JSH
