University of Maryland researchers have developed Alibi Routing, a method for providing concrete proof to Internet users that their information did not cross through certain geographic areas.
The system is ready to deploy and does not require modifications to the Internet's routing hardware or policies.
The researchers evaluated the Alibi Routing method by simulating a network with 20,000 participants and selected countries known as "Enemies of the Internet," including China, Syria, North Korea, and Saudi Arabia, as well as Japan and the U.S. because those countries had the highest number of Internet users at the time.
Alibi Routing works by searching a peer-to-peer network to locate other users running the software that can relay the initial user's packets to their ultimate destination while avoiding specified forbidden regions. The peer, dubbed an alibi, provides proof that at a particular time, a packet was at a specific geographic location far enough away from the forbidden areas that data could not have entered them.
The success rate for Alibi Routing depends on how close the source and destination are to the forbidden region and how central the forbidden region is to Internet routing. The simulation showed the system successfully found an alibi more than 85 percent of the time, and when a small safety parameter was implemented, the success rate rose to 95 percent.
