This Fall Nikita and I would be teaching a new course called Applied Cryptography. The plan is to cover the basic theory of “modern” cryptography and also look at several applications where these concepts are/should be used. One of the goals of the course, in my view, would be to teach as little as possible 
Well, or rather, teach a few fundamental concepts which manifest in different ways (and unfortunately under different names) in various applications.
We don’t have a public webpage for the course yet, but we’ll get to it after both of us are in town, before the classes start.
Since Nikita and I’ll be taking turns lecturing, this time, I’ll hopefully get around to posting more here, on this blog. To get things started, what’s better than a video on youtube? Here’s a “Google Tech Talk” bemoaning some of the pitfalls in applying cryptography. (It may or may not make sense to you, but the bottom line is that you need to take this course before using any crypto stuff )
