Abstract
A secure method and a secure provision unit provide a secured replica pseudo random noise signal for a receiver unit. A replica pseudo random noise code is modulated with a noise signal by a receiver-end provision unit. The replica pseudo random noise code has artificially produced noise superimposed thereon, so that the replica pseudo random noise code cannot be read from the noisy signal even at the receiver end, for example within a receiver or on a transmission path between provision unit and receiver.
