he invention relates to a method establishing a safe and quick communication between two or several persons using digital communication and data transmission systems. A mathematical method of discontinuous dynamical systems employed for the creation of random authentication keys can be utilised. The possibility of creating a theoretically infinite number of authentication keys of any length, the absolute random form and the facility of creation and use thereof permit the application of an "onetime pad" protocol offering the respective communication safety. The creation and distribution of a precise algorithm depends on a plurality of initial parameters ranging from some decades to many thousands according to the desire of the user and the required safety level. Safety and flexibility make said new method particularly useful to applications of digital communication and transmission data where difficulties issued from the lack of safety and problematic use are particularly acute. Theinitial communication between two users for the starting of the protocol can be accomplished in a safe manner, with the use of one of the known protocols of the quantum authentication keys distribution. After the initial communication has been started, the proposed protocol gives the possibility of an infinitum safety communication, with the interchange of ordinary messages, via the network (e.g. Internet). |
