My only complaint is that the math, which the comic spends a great deal of time discussing, is far less important than the non-obvious potential attacks and pitfalls in implementation (things like ECB).

@nick ... then this isn't really aimed at you.

In earlier stages of learning, simply keeping track of the parts of the process and how they inter-relate is a key learning goal. The parts you are concerned about are indeed important - but only after the student demonstrates some fundamental understanding of how an encryption protocol would operate in the first place.

And here I expected something from XKCD...
Pretty nice, although my head started to hurt towards the end... It is late Friday afternoon after alll. ;)

At least he's holding off on posts about the big arrest and the other "given a fake device" arrests. I have to admire a guy that doesn't jump right on the story of the moment. Thanks.

Damn, A non E mouse beat me to saying that.

I wonder if Mr. Monroe is reading this right now?

Love the way it goes through at more and more detailed levels. I could nitpick some things, of course, but basically it's great.

Nice enough, but not nearly as entertaining as the stick figure explanation of AIG.

"A posting AFTER the Friday Squid? What is this world coming to?"

I'm not quite sure what happened either.

@ Bruce,

"I'm not quite sure what happened either."

You don't even have the old "Concord flyer" excuse of "you arrived before you left"...

Sophomoric at best.

Nostromo • September 28, 2009 3:45 AM

It's very good.

Stick figures can be expressive. I thought the "little Bobby Tables" xkcd strip was the best introduction to some SQL vulnerabilities I'd seen.
