Secure Symmetric Key Exchange

Authors: Michel SJ Kuipers

Exchanging a secret password or key over an insecure communication line (symmetric key exchange) traditionally always causes the problem that a man-in-the-middle can eavesdrop the communication between the two parties and the intercepted data together with the known algorithm provides a way to deduce the password, making every attempt insecure. The solution is to use asymmetric key exchange using very complex mathematical formulas which are almost impossible to inverse, invented by Diffie and Hellman. This article proposes a new invention which is very simple and elegant, and fast to compute, which should make symmetric key exchange logically proven safe (unhackable) and easy to use, solving this old problem in perpetuity.
