Scientists at MIT created an anonymous system exchange messages, με το όνομα Vuvuzela, το οποίο ανήκει στην ίδια κατηγορία με το Tor, I2P, και HORNET, έχοντα όμως μια διαφορετική προσέγγιση για την αναμετάδοση των μηνυμάτων μεταξύ των δύο μερών.
The system, named Vuvuzela, following the infamous plastic horn used at the 2010 FIFA World Cup in South Africa, is currently in its infancy, but researchers praise the unique technique of.
Unlike Tor, which hides the messages with multiple layers of encryption to send them through random servers on the Internet, Vuvuzela takes a different approach, which uses less encryption but a lot of traffic moves.
Vuvuzela, like is described by the four researchers who created it, receives the messages from a sender and stores them in a memory address on one of its many interconnected servers, called mailboxes.
Before you decide where to store its content, the message goes through different servers that send traffic movements to all interconnected users.
The server notifies the recipient that there is a message for him / her who goes to receive it, and passing through various mailboxes to reach the message position. When a connection through one of these mailboxes is made by a recipient who searches for his message, each of these servers sends packets of motion to the network.
With so much false traffic, as well as senders and recipients moving to their destinations to deliberately create even more fake traffic until the real message is retrieved, you can imagine how much data an attacker should evaluate before getting an indication of who talks with whom.
MIT researchers claim that even if attackers penetrate more than half of their messaging network and if at least one mailbox server is left intact, users will be able to communicate securely with false traffic.
A Vuvuzela test network was created, using Amazon's EC2 servers and 1 million simulated users. Early results showed that the Vuvuzela managed to exchange over 15.000 messages per second, with a delay of 44 seconds. Yes, the latency is long, but this was a first essay.
"We think these results are encouraging, as they show that Vuvuzela can be scaled up to a reasonable number of users, and its latency can be acceptable for email or chat," the researchers said after the first test.
