SHIFT REGISTER technology

The stuff on linear and non-linear shift register sequences which is now
appearing on jya.com is the �military-grade� crypto technology.

Semionoff and http://www.jya.com/crack-a5.htm contains material similar
to 
what I saw Brian Snow present in schematics of NSA KG units.

The statement by [email protected]

  The A5 algorithm uses a three level, non-linear feedback shift
  register arrangement, designed to be sufficiently complex to resist
  attack.

points to the technology used for military-grade crypto.

The reason NSA regarded the R register, seen at
http://jya.com/whpfiles.htm,
feedback function classified was that it contained a non-linear feedback
function.  

I was ORDERED to build UNCLASSIFIED hardware.  This is why I stuck the R
register
feedback function in a fast ram.

This similarity between the structure of the nonlinear feedback function
in the 
CAVE algorithm seen at 

  http://www.semionoff.com/cellular/hacking/phreaking/

to the feedback function published in my SAND report

: A11   A1 A5 AND
        A1 0= A9 0= AND XOR
        A6 A10 XOR XOR ;

reveals  �military-strength� technology.  

SHIFT REGISTERS.

Words �shift registers� also caused the Great American Spy Sting bust.

The Cold War is over.  And the crypto cat is now about fully out of the
bag.

Let�s hope for settlement so that we can all go on to more constructive
tasks.
