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.
