Quantum cryptography outperformed by classical technique
June 17, 2012
The KLJN scheme is a statistical-physical competitor to quantum communicators whose security is based on Kirchhoff's Loop Law and the Fluctuation-Dissipation Theorem (credit: R. Mingesz et al)
The secrecy of a controversial new cryptographic technique is guaranteed, not by quantum mechanics, but by the laws of thermodynamics, say physicists, Technology Review Physics arXiv Blog reports.
Laszlo Kish at the Texas A&M University in College Station and associates have found another way to send information, which they claim guarantees complete security, guaranteed by the second law of thermodynamics.

Only if you encrypt it well Gordon :)

That’s exactly what I was going to say…but should I dare to say anything in front of you, Marcos.

I see they are already using it to hide more descriptive press releases…
