One-Way Indexing for Plausible Deniability in Censorship Resistant Storage

 The fundamental requirement for censorship resistance is content discoverability — it should be easy for users to find and access documents, but not to discover what they store locally, to preserve plausible deniability. We describe a design for "one-way indexing" to provide plausibly-deniable content search and storage in a censorship resistant network without requiring out-of-band communication, making a file store searchable and yet self-contained. Our design supports publisher-independent replication, content-oblivious replica maintenance, and automated garbage collection.
