Providing a secure replica pseudo-random noise signal

摘要

The invention relates to an improved secure method and to a secure provisioning unit for providing a secure replica pseudo-random noise signal to a receiver unit, wherein a replica pseudo random noise code is modulated by a receiver-side providing unit with a noise signal. The replica pseudo-random noise code is overlaid with artificially generated noise, so that the replica pseudo-random noise code can not be read from the noisy signal on the receiver side, for example within a receiver or on a transmission path between the providing unit and the receiver.
