Distributed storage systems
We are pushing the limits of today’s distributed storage systems on several fronts. Scatter, a scalable peer-to-peer key-value storage system, preserves serializable consistency even under adverse conditions. Comet is a distributed key-value store that lets clients inject snippets of code into storage elements, creating an active key-value store that greatly increases the power and range of applications that use distributed storage applications. Faculty: Anderson, Kohno, Krishnamurthy, Levy.
Privacy-preserving data sharing
Increasing interconnectivity and data sharing can compromise data security and privacy. OneSwarm is a peer-to-peer tool that provides users with explicit control over data privcy by letting them determine how data is to be shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, shared with friends, shared with some friends but not others, and so forth -- an approach we termed friend-to-friend (F2F) data sharing. Faculty: Anderson, Krishnamurthy.
Reverse Traceroute
Traceroute has long had a fundamental limitation that affects all these applications: it does not provide reverse path information. In this project, we address this longstanding limitation by building a reverse traceroute tool. Our tool provides the same information as traceroute, but for the reverse path, and it works in the same case as traceroute, when the user may lack control of the destination.
