Abstract
In a method for generating a secret key, a first node which is connected via a transmission channel to a second node estimates a variability of the transmission channel with regard to at least one physical channel parameter of the transmission channel, selects a sampling rate for the channel parameter as a function of the variability, generates a bit sequence by sampling the channel parameter at the selected sampling rate, and adjusts the bit sequence with the second node.
