Research output: Chapter in Book/Report/Conference proceedingConference contribution


In this paper, we consider new issues in building secure p2p file sharing systems. In particular, we define a powerful adversary model and consequently present the requirements to address when implementing a threat-adaptive secure file sharing system. We describe the main components of such a system: An early warning mechanism to perform pre-emptive actions against new vulnerabilities; a mechanism to sanitize corrupted nodes; a protocol to securely "migrate" data from non-safe nodes; and an efficient dynamic secret sharing mechanism. © 2007 IEEE.
