You can't do security without THIS

Every secure communication protocol will at some point require some sort of Key Exchange. In this video we discuss the concept of a Key Exchange, and illustrate the problem that a Key Exchange is trying to solve. We then explain simply how that problem is solved. Finally, we introduce the two algorithms that can be used to do the actual math of a Key Exchange: RSA and DH. Which will each be covered in the next couple of lessons. // CHAPTERS 0:00 - Intro 0:20 - The Key Exchange Problem 1:17 - The solution 1:34 - What is a Shared Secret? 2:52 - Shared Secret vs Secret Key 3:21 - Two Key Exchange Algorithms: RSA & DH // FULL SERIES - Cryptography Essentials // This video is part of a 16-part series covering the essentials of modern Cryptography.
