MIT Creates messaging system which becomes unsniffable through chaffing data: Vuvuzela

Vuvuzela relies on dummy traffic to hide the real connections

Before it’s decided where to store its content, the message goes through different servers, which send out dummy traffic to all interconnected users.

The server notifies the recipient that there’s a message for them, the user then goes to retrieve it, also passing through different mailboxes to get at the message’s location. When a connection is made through one of these mailboxes by a recipient searching for their message, each of these servers sends out dummy network packets on the network.

With so much fake traffic, and with senders and recipients moving past their destinations to intentionally create even more fake traffic after they’ve left or retrieved the actual message, you can only imagine how much data an attacker would have to sniff out before getting a clue of who’s talking to whom.

MIT researchers claim that attackers can even infiltrate more than half of its mailbox network, but if at least one mailbox server is left intact, users will be able to safely communicate because of all the fake traffic.
