چکیده
Kirchhoff-Law-Johnson-Noise (KLJN) secure key distribution (Cho 2005),(Palmer 2007), (Kish 2006), (Mingesz 2013),(Kish 2009),(Mingesz 2008),(Kish 2006b), is a classical physical scheme that is a potential alternative to quantum key distribution. It is also sometimes loosely referred to as the Kish cipher, however, it is a hardware-based scheme for securely distributing cipher keys, and is not a cipher in itself.

Random-resistor-random-temperature Kirchhoff-law-johnson-noise (rrrt-kljn) Key Exchange
We introduce two new Kirchhoff-law-Johnson-noise (KLJN) secure key distribution schemes which are generalizations of the original KLJN scheme. The first of these, the Random-Resistor (RR-) KLJN scheme, uses random resistors with values chosen from a quasi-continuum set. It is well-known since the creation of the KLJN concept that such a system could work in cryptography, because Alice and Bob c...
متن کاملCracking the Bennett-Riedel secure scheme and a critical analysis of their claims about the Kirchhoff-law-Johnson-noise system
Recently, Bennett and Riedel (BR) (http://arxiv.org/abs/1303.7435v1) claimed that, in the Kirchhoff-law-Johnson-noise (KLJN) classical statistical physical key exchange method, thermodynamics (statistical physics) is not essential and that the KLJN scheme provides no security. They attempt to prove the no-thermodynamics view by proposing a dissipation-free deterministic key exchange method with...
متن کاملOn KLJN-based secure key distribution in vehicular communication networks
In a former paper [Fluct. Noise Lett., 13 (2014) 1450020] we introduced a vehicular communication system with unconditionally secure key exchange based on the Kirchhoff-Law-Johnson-Noise (KLJN) key distribution scheme. In this paper, we address the secure KLJN key donation to vehicles. This KLJN key donation solution is performed lane-by-lane by using roadside key provider equipment embedded in...
متن کاملEnhanced secure key exchange systems based on the Johnson-noise scheme
We introduce seven new versions of the Kirchhoff-Law-Johnson-(like)-Noise (KLJN) classical physical secure key exchange scheme. While these practical improvements offer progressively enhanced security and/or speed for the non-ideal conditions, the fundamental physical laws providing the security remain the same. In the "intelligent" KLJN (iKLJN) scheme, Alice and Bob utilize the fact that they ...
