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 system’s 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.
