“Hey, Joey, ‘splain me public key cryptography!”

Joey deVilla explains public key cryptography for non-geeks:

Have you ever tried to explain public-key cryptography (a.k.a. asymmetric cryptography) or the concept of public and private keys and what they’re for to non-techies? It’s tough, and I’ve spent the last little while trying to come up with an analogy that’s layperson-friendly and memorable.

It turns out that it already exists, and Panayotis Vryonis […], came up with it. Go over to his blog and check out the article titled Public-key cryptography for non-geeks. Whenever I have to explain what private keys and public keys are for to someone who’s new to cryptography, I use Vryonis’ “box with special lock and special keys” analogy. Not only does the explanation work, but it’s so good that the people I’ve used it on have used it themselves to explain public-key crypto to others.

I’ve recently used Vryonis’ analogy in a couple of presentations and thought I’d share images from my slides. Enjoy!
