METHOD FOR GENERATING A SECRET BETWEEN USERS OF A NETWORK, AND USERS OF THE NETWORK WHICH ARE CONFIGURED FOR THIS PURPOSE

摘要

A method for generating a shared secret between a first user and a second user of a network is provided. The first user receives from the second user a first training sequence via a communication link between the first user and the second user. The first user ascertains at least one first value for at least one physical property of the communication link, and determines a portion of the shared secret as a function of the first value. A comparison of the first value to at least one threshold takes place for determining the portion of the shared secret. The first user transmits the first training sequence to the second user via the communication link, and adapts the transmission parameters of the first training sequence as a function of the position of the first value relative to the threshold.

1. A method for generating a shared secret between a first user and a second user of a network, the method comprising:
receiving, at the first user, from the second user a first training sequence via a communication link between the first user and the second user; ascertaining, by the first user, at least one first value for at least one physical property of the communication link; determining, by the first user, a portion of the shared secret as a function of the first value; comparing the first value to at least one threshold for determining the portion of the shared secret; and transmitting, from the first user, the first training sequence to the second user via the communication link; wherein the first user adapts transmission parameters of the first training sequence as a function of the position of the first value relative to the threshold.
