Kirchhoff's-Law-Johnson-Noise
secure key distribution


The Kirchhoff-Law-Johnson-Noise (KLJN) secure key exchange system has been introduced as a simple, very low cost and efficient classical physical alternative to quantum key distribution (QKD) systems. The ideal system uses only a few electronic components - resistor pairs, switches and interconnecting wires - to guarantee perfectly protected data transmission.

Our related research include both theoretical and experimental investigations, the aim is to find new ideas, methods and to support practical applications.
