This project investigates the resiliency of Peer-to-Peer (P2P) overlay networks - based on both structured topology as well as a social network-based topology - against partitioning attacks targeting a relatively small fraction of the overlay network (e.g. 0.5% of the network is "cut"). An example of this might be a Government that disconnects the Internet in the country from the rest of the world (while allowing networking inside). FutureGrid cloud and if needed large-memory resources will be used for graph simulation and evaluation.
Intellectual MeritFirst, we would like to investigate the resiliency of Peer-to-Peer (P2P) Structured Overlay Networks (SON) against partitioning attacks targeting a relatively small fraction of the overlay network (e.g. 0.5% of the network is "cut"). An example of this might be a Government that disconnects the Internet in the country from the rest of the world (while allowing networking inside). What fraction of users in that country would still be able to communicate among each other, after the partitioning attack? How worse does it get when a significant fraction of the nodes are behind different NATs? And what about if the adversary colludes with a small fraction of the users within the small disconnected component? Furthermore, we want to evaluate this hypothesys: is a Unstructured Overlay Network (UON) based on social relations more resilient than a SON, against the attacks described above?
Broader ImpactsThis project has potential broader impact on peer-to-peer systems that are able to better maintain connectivity among users in the face of large network partitions.

Resource Requirements
- Hardware Systems
-
- alamo (Dell optiplex at TACC)
- india (IBM iDataPlex at IU)
- bravo (large memory machine at IU)
FutureGrid will be primarily used by graduate students to deploy virtual machines to run simulation experiments.
Scale of UseThe anticipated scale of use is a few VMs (typically one) with relatively large memory (16GB+) deployed for a few hours at a time.
