From Simple English Wikipedia, the free encyclopedia Kerckhoffs's principle ( axiom, or law) is an idea in cryptography. It was stated by Dutch cryptographer Auguste Kerckhoffs in the 19th century. It is: "A cryptosystem should be secure even if everything about the system, except the key, is public knowledge".

Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell.

Oct 04, 2013 · For purposes of analysing ciphers, Kerckhoffs' Principle neatly divides any design into two components. The key can be assumed to be secret for purposes of analysis; in practice various measures will be taken to protect it. Everything else is assumed to be knowable by the opponent, so everything except the key should be revealed to the analyst.

Kerckhoffs's principle (also called Kerckhoffs's desideratum, assumption, axiom, doctrine or law) of cryptography was stated by Netherlands born cryptographer Auguste Kerckhoffs in the 19th century: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge.

In cryptography, Kerckhoffs' principle (also called Kerckhoffs' assumption, axiom or law) was stated by Auguste Kerckhoffs in the 19th century: a cryptosystem should be secure even if everything about the system, except the key, is public knowledge.
