| Abstract | it has been shown that thermal noise and its electronically enhanced versions (Johnson-like noises) can be utilized as information carrier with peculiar properties.
Relevant examples are "Zero power communication", "Unconditionally secure classical communication with Johnson(-like) noise and Kirchhoff loop" and "Noise driven computing". 1. Zero power communication (stealth communication) utilizes the equilibrium background noise in the channel to transfer information. 2. Unconditionally secure communication is based on the properties of Johnson(-like) noise and those of a simple Kirchhoff's loop. The scheme utilizes on the robustness of classical information and the second law of thermodynamics. It uncovers active eavesdropping within a single clock period (no error statistics is required) and it is naturally protected against the man-in-the-middle attack. Even though a practical system is never ideal, the engineering is straightforward to make the practical raw-bit security greater than quantum raw-bit security. The first practical realization of the communicator device consists of two computer cards and it is successfully tested beyond the quantum range, up to the range of 2000 km. Because the circuitry can easily be integrated on computer chips, unconditionally secure computer processors, memories and other hardware can be realized. 3. Noise driven logic offers lower energy dissipation for computing and shows interesting new properties to be discussed during the talk. |
