| Kirchhoff's-law-Johnson-noise
(KLJN)
secure key distribution Unconditionally (information-theoretically) secure
key exchange scheme based on:
Johnson-noise (Fluctuation-dissipation
theorem) at enhanced temperatures;
Kirchhoff's laws; and the properties of
Gaussian stochastic processes.
Unconditional (information-theoretic) security:
Eavesdropping does not provide any knowledge about the encryption key
and the message. Currently only KLJN and quantum encryption can claim
unconditional security. KLJN is wire-based and this is the only
unconditionally secure hardware that can be integrated on a chip to secure credit cards, computers and instruments.
Opposite to conditional security (which is typical today). Examples: all the software based solutions,
practically everything today. Eavesdropping can crack the encryption if
enough resources are available. It is "mathematically zero" information
theoretic security.
