THE PROBLEM OF INFORMATION LEAK DUE TO PARASITIC LOOP CURRENTS AND VOLTAGES IN THE KLJN SECURE KEY EXCHANGE SCHEME

2019 Polish Academy of Sciences. All rights reserved. The Kirchhoff-law-Johnson-noise (KLJN) secure key exchange scheme offers unconditional security, however it can approach the perfect security limit only in the case when the practical systems parameters approach the ideal behavior of its core circuitry. In the case of non-ideal features, non-zero information leak is present. The study of such leaks is important for a proper design of practical KLJN systems and their privacy amplifications in order to eliminate these problems.
