Optical Cryptography

chill writes: "In Cryptonomicon, Neil Stephenson wrote about Bell Labs' research into using static, or chaotic signals to mask communications. A message would be generated, then the signal masked in noise. Someone on the other end would subtract out the noise to get the signal. Works great if both ends have the exact same noise. Now, Jia-ming Liu, professor of electrical engineering at UCLA, is giving a presentation on doing essentially the same thing using OC-48 (2.5 Gbps) optical circuits. The presentation will be at the upcoming Optical Fiber Communications Conference and Exhibit. There is an article covering this and some other nice advances in optical over in Wired."

Important Linux news (not a troll! check proofs!)

[Anonymous Coward]

I would like to bring to the attention of my fellow Slashdot readers some troubling news: Linux is being used by Al Qaeda, Abu Sayyaf, and other terrorist organizations with equally cool sounding names as an affordable and powerful tool for purposes of recruitment, passing coded messages regarding planned terrorist operations, and other insidious purposes. I will attempt to show some of the more obvious proofs I have discovered to back up my arguments.

• The presence of an Islamic calendar (cal-islam.elc) as included with the xemacs package. This calendar is likely being used for determining significant dates (such as September 11) for terrorist attacks.
• The word "terror" is mentioned several times in the Linux kernel source code (svr4.c in the abi/svr4 directory). This file was written by Mike "Jagdis" whose name itself is an obvious Islamic reference to terrorism.
• The phrase, "terrorist act" is actually present in drivers/char/ip2main.c.
• There are several
  references to the WTC buildings, again in the Linux kernel source code (in the drivers/scsi directory).
• The freetype code includes the file internal/tterrors.h -- an obvious reference to "international terrorism".
• Various files in drivers/char and drivers/scsi refer to "religious disputes" and "religious issues" (likely, the issues between God fearing American christians and evil Islamic terror mongers).
• The word "plane" (a reference to the tragic airplane hijackings of September 11th) appears in several places in the drivers/char/drm directory.
• Various references to the words "evil", "destroy", "bomb", "warrior", and "hate" scattered in places too numerous to mention.
• The word "hijack" appears in Documentation/kernel-docs.txt, and "hijacking" in drivers/char/ChangeLog, which is also an obvious suggestion for future attacks.
• The file fs/jffs/intrep.c contains the phrase, "Might as well commit suicide", which is an obvious suggestion to would-be terrorists to
  commit suicide bombings.
• One of the maintainers goes by the name, "Andreas Bombe", with the e-mail address, andreas.bombe@munich.netsurf.de. Obviously this is a hidden message indicating the next target for terrorist bombings is some place in Munich, Germany.
• Take a look at the book cover of ``Professional Linux Programming'' and decide for yourself which of the 15 authors has obvious terrorist links.

I am sure I have only scratched the surface of this disturbing conspiracy. I strongly urge the Slashdot readership to support American companies such as Microsoft who only hire patriotic American citizens and to boycott any company which is involved with Linux (as they are directly supporting terrorists). I sincerely hope the CIA or FBI can look into the actions of
open source developers. People like Linus Torvalds should be taken into custody and have all assets seized.

Act now before it is too late!

The same noise ... old folks can relate

"Someone on the other end would subtract out the noise to get the signal. Works great if both ends have the exact same noise."

I know some older folks who think that two people with "Metallica - Injustice for All" have the same noise. Is this what they are referring to here? &^}

But seriously, if two people have 'the same noise' and use it to decrypt, it can't possibly be considered noise. It become a signal. No two ways about it. Think people ... think!
