Abstract

A method for generating a secret key via a reciprocal communication channel connecting a first communication node and a second communication node, wherein the first communication node obtains a first sample by a measurement of the communication channel, the first communication node performs a quantization of the first sample, the first communication node performs a matching of the quantized sample with the second communication node via the communication channel, during the matching, the first communication node obtains and quantizes a second sample by a second measurement of the communication channel and the communication nodes obtain the key from the samples by a privacy amplification.
