Method for generating a key in a network and users configured for this purpose

摘要

A method for generating a shared key between two users of a network. The two users respectively have at least one clock as well as an arrangement for detecting a certain surroundings variable. The two users detect the certain surroundings variable synchronously at respectively predefined points in time or start a detection of a course of the surroundings variable. Finally, the two users respectively generate the shared key taking values detected in this manner for the surroundings variable into account.
