Robert Meier gave an interesting presentation on the basics of public-key cryptography, including discussions of how it works, and what conditions need to be met to have it work well.

Robert sent me a copy of the slideshow which his presentation was based on, but at present, I am not able to upload this. I will do so as soon as I figure out how to do it. In the meantime, if you would like a copy of this, please email me privately (shayw@controlmanagement.com), and I will be glad to send you a copy of it.
