Fictional characters to arrange key exchange over unsecure channel?
July 21, 2014 6:29 PM Subscribe
I'm presenting a cryptography demonstration to a small group of nerdy teenagers soon. As part of the fun, I have an activity in which they are spies that need to arrange a key exchange over a unsecure channel without any required prior knowledge of each other. (You can assume the mechanics of the key exchange are sound.) I thought it might be fun if I could refer to different fictional characters that the teens could pretend to be. What are some fictional characters and associated unsecure channels that would fit the scenario above? Examples and further notes inside.

The activity I'm using is susceptible to Man in the Middle Attacks (pretending to be the other person to both parties in order to gain access to the information), so naming the character or entity that might serve as the man in the middle would be a bonus.
The characters can certainly know each other, but don't *have* to know anything about each other, except that they'll be performing this key exchange.
Here're a couple examples I've come up with:
Aurors from Harry Potter, via owls, Man in the Middle could be a set of Death Eaters
Agents of SHIELD/Avengers, via facebook or other common social networking site, Man in the Middle: HYDRA
Assume that the teens who are hearing this presentation are from or have spent significant time in the USA.
