Spooks' secret TEMPEST-busting tech reinvented by US student

A British, An American And A German Engineer

The Brit: Oh that's a heinously difficult problem. How can we possibly transmit data through steel ?? Maybe we should ask the BOFFINs in Cambridge. X-Rays ? Hidden dimensions ?? This is a tough problem.

The American: We need to maximize transmission capacity. Let's call Xilinx to order 500 of the fattest FPGAs and Intel for 7000 x86 CPUs we will stuff into the submarine. Then Admiral McFart and Admiral McWarmonger can do a video conference over the transducer. Proceeds to work long hours in the lab.

The German: Shannon's Channel capacity determines maximum bandwidth if you wanna know, Captain. How much bandwidth do we need if officers can use a keybord ? Ah, we need 2500 baud AND we can use some nifty crypto which <CLASSIFIED WORD A> <CLASSIFIED WORD B> .

A single 68000 and a run-of-the mill transducer from the grabbag do. Let's wire it up the next two days and then go for Beer and Schweinshaxen. Proesterchen !

Libya's internet goes dark as upheaval spreads

Libyians, Use Cryptology !

You should be aware of the fact that the tyrant has purchased a lot of Communications Intelligence Equipment from various countries, including Europe.

All you say on HF/UHF Radio can be intercepted !

All you say on mobile phones can be intercepted !

Your position can be geo-located and by used for air attacks ! It can be used to provide warning to the tyrant's troops

To succeed you should

* organize yourself. Military and educated persons must be leaders.

* encrypt all communications. (see below)

* read about military tactics and strategies (see below)

* be as brief as possible on the radio; use the lowest possible power setting

* use Yagi antennas to reduce emissions

For reasons I cannot reveal, all I can do is to provide my skills as a programmer. I have written a cipher for you:

(it will compile on Linux using g++; wordpress does not display the include statements correctly)

Another cipher:

(might be broken by powers friendly to the tyrant, be careful)

Military tactics and strategy:

Your cause is noble, you are strong fighters and if you also teach yourself military skills quickly, you will succeed. Freedom for Lybia !
