Create a system by which two parties can communicate but an eavesdropper has difficulty even telling that a message is being sent.
One solution is to piggyback on a system which is constantly sending messages, and messages are routed through multiple hops. Can Freenet work for this purpose?
Global traffic analysis, looking at message sizes and timing, might be enough for an eavesdropper to connect the two parties. Maybe nodes can collect messages over a time period and send them to another node as a bundle. This disguises message sizes and introduces more delays making timing analysis difficult.
Inspired by David Petraeus and Paula Broadwell communicating through Gmail drafts of a shared account. What if it was far more difficult to tell that either of them was connecting to a common service?
