Abstract

The invention seeks to facilitate the encryption of data information in a two-way point to point connection between two subscribers.Via the exploitation of purely random digital sequences of an unknown length, the encryption is practically impregnable. The main principle behind the invention is that the receiving subscriber's random sequence (B1, B2) is used for the communication (D1, D2) directed to this, and the random sequence count is transferred between the subscribers in a particular loop (b, c) where they encrypt each other. A form of key distribution is not needed.<IMAGE>
