Abstract
A method for generating a secret key shared by a group of at least three terminals from characteristics of wireless communication channels connecting the terminals in twos, including, at each of the terminals of the group, the implementation of the following steps of: acquiring signals from wireless communication channels, known as adjacent channels, connected to the terminal and generating a representation of each adjacent channel; for at least one wireless communication channel, known as a non-adjacent channel, not connected to the terminal, acquiring at least one image signal of the non-adjacent channel and generating a representation of the non-adjacent channel, determining the secret key from a combination of the representations of the adjacent channels and at least one representation of non-adjacent channel.
