Totally secure classical networks with multipoint telecloning (teleportation) of classical bits through loops with Johnson-like noise

Laszlo B. Kish, Robert Mingesz

First, we show a new inexpensive defense against intruders and the man-in-the-middle attack in the Kirchhoff's-loop-Johnson-like-noise (KLJN) cipher. Then instead of point-to-point…
