One-way indexing for plausible deniability in censorship resistant storage
Eugene Y. Vasserman, Victor Heorhiadi, Yongdae Kim · 2013
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 outof-band communication, making a file store searchable and yet self-contained. Our design supports publisherindependent replication, content-oblivious replica maintenance, and automated garbage collection. 1
