Kish Cypher, The: The Story Of Kljn For Unconditional Security

An objective monograph on the "Kish Cypher" (the popular but incorrect name for the Kirchhoff - Law - Johnson - Noise scheme), this unique volume introduces the facts on the method from the perspective of Dr Kish himself. Designed to offer a thorough account of the cypher and its unconditionally secure communication, the text explains the cypher's foundation in classical physics and its superiority to its quantum-based competitors. This book seeks to clarify the misinformation behind heated debates on Wikipedia, and debunk the common misconception of "Kirchhoff's law" using simple and clear-cut treatments to explain the cypher's working principal - an understanding that has eluded (even) some experts on software-based security or quantum security - and how it can provide the same (or higher) level of security as quantum communicators at a thousandth of the cost. Straight out of both hard and popular sciences, the explanations provide both the big picture and the genesis of the ideas behind the cypher - complete with personal history beyond the invention, as well as reflections on the current situation of science and technology (including defense technology) and academic life in the USA and the Western world. The contents of this text include layman introductory and concluding summaries for each chapter - allowing both professionals and interested members of the public to benefit from reading it.

Summary

Description

Designed to offer a thorough account of the KLJN key exchange system (also known as the Kish Cypher, the Kish Key Distribution, etc.) and its unconditional security, this book explains the scheme's foundation in classical statistical physics and its superiority to its quantum-based competitors for particular applications, from the perspective of Dr. Kish himself.This book clarifies the misinformation behind heated debates on the 'Kish Cypher' (the popular but incorrect name for the Kirchhoff-Law-Johnson-Noise, KLJN, scheme), and debunks common misconceptions by using simple and clear-cut treatments to explain the protocol's working principle - an understanding that has eluded (even) several experts of computer science, quantum security, and electrical engineering. The work also explains how the scheme can provide the same (or higher) level of security as quantum communicators at a thousandth of the cost.The contents of this text address both layman and expert levels of understanding.
