Why wave-based classical communicators can never be totally secure?
arXiv:physics/0610102
Abstract
Recently, we proposed a classical communicator which was inspired by the Kirchhoff-loop-Johnson-like-Noise (KLJN) communicator and was claimed totally secure. Here we withdraw this claim and prove that, similarly to earlier intuitive suspicions, a wave-based classical communicator can never be totally secure.
