Several readers sent in an update on DTN, the interplanetary Internet protocol
Please stop screwing up the meaning of DTN. Not just
A DTN protocol is one that takes advantage of the ephemeral connectivity of DTNs, usually along the lines of employing the store, carry, and forward approach to getting data from A to B via a time-varying path; e.g. a path exists, just not at any point in time.
What Cerf has done has create a bundle forwarding protocol stack for the Android. It's not as "out there" as you'd think- someone send you data, you carry it, then forward it later. Lots of questions/issues in between as you might imagine.
I think some people like Kevin Fall need to get more credit for their contribution to this area of research.
Disclaimer: I am NOT Kevin Fall but I am a network researcher, specifically in the area of DTNs. No, not the algorithm.
The only thing the Iran regime would need to do [...] would be to setup a lot of TOR nodes and analyze the traffic going through them
This is exactly what TOR was designed to protect against. Even a large scale compromise fails to do two things:
1. Compromise user identity (e.g. originating IP address), and
2. Analyze packets non-discretely (e.g. as streams).
So the most they'd be able to determine is how much traffic is coming from what appear to be other relays, and also that it is encrypted. They probably wouldn't even be able to decrypt a single block of data - it's like solving puzzles within puzzles, where the shapes of the pieces are constantly changing.
People will buy anything that's one to a customer.
