 # Concept Glossary
 
-There are a lot of ways to talk about the topics and concepts underlying digital security, and the example that really clicks can be different for every person. This resource is less a glossary than a round-up of great analogies and explanations, offering simplified explanations of technical concepts for non-technical users.

-### Key-Based Authentication
-
-Seth Schoen leads a great workshop on key based authentication, and the analogy he uses is this: If you remember anything about mathematics, you might remember that one pretty easy thing to do is to multiply two really big numbers together. It takes time, if you're only using a pencil, but you can do it. Factoring the product of two primes, however, is a lot harder. You can think of key-based encryption as taking advantage of this disparity.

 ## Authentication
 
 The [passwords lesson](Chapter02-06-Passwords.md) is a great resource for explaining the process of authentication. But at its core, "authentication" is just the process that a system uses to determine that you are who you say you are.
