Abstract

Online social networks, censorship resistance systems, document redaction systems and health care information systems have disparate requirements for confidentiality, integrity and availability. It is possible to address all of these, however, by combining elements of research in both filesystems and security protocols. We propose a set of techniques and combinations that can be employed to move beyond the current centralized/decentralized dichotomy and build a privacy-preserving optionally-distributed cryptographic filesystem. Such a filesystem, prototyped as UPSS: the user-centred private sharing system, can be used to build applications that enable rich, collaborative sharing in environments that have traditionally either avoided such interaction or else suffered the costs of out-of-control sharing on untrustworthy systems. We believe that our combination of filesystems and security protocols research demonstrates that sharing and security can go hand in hand.
