Diffie-Hellman Key Exchange - A Non-Mathematician's Explanation

Diffie-Hellman Key Exchange - A Non-Mathematician's Explanation

Cover
What is Diffie-Hellman (DH), and why should you care? DH is a mathematical algorithm that allows two computers to generate an identical shared secret on both systems, even though those systems may never have communicated with each other before. That shared secret can then be used to securely exchange a cryptographic encryption key. That key then encrypts traffic between the two systems.

This paper will help you to understand the Diffie-Hellman key exchange protocol . . . without digging through the math by presenting several key diagrams and explanations.
