Friday 4/24/98 7:33 AM John Young J Orlin Grabbe John Gilmore 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 david.loos@eudoramail.com 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. http://caq.com/CAQ/caq63/caq63madsen.html The Cold War is over. And the crypto cat is now about fully out of the bag. Lets hope for settlement so that we can all go on to more constructive tasks. Later bill
