Censorship-Resistant File Storage
نویسندگان
چکیده
This project tackles the problem of designing a file system that is resistant to censorship; that is the deletion, alteration, or distribution of a user’s data that is hosted by a third party. Third party and cloud hosting is getting more popular, and finding ways to protect yourself against these kinds of attacks has become ever more important. Our group presents Storj, a decentralized peer-to-peer file storage system that achieves this protection while also allowing for reasonable data availability and integrity. Finally, we discuss Storj Sync (https://github.com/rtran9/ 6.857-storj-sync), a client side tool to increase usability with a relatively new and growing system.

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 outof-band communicatio...
متن کاملProof-of-Censorship: Enabling centralized censorship-resistant content providers
Content providers often face legal or economic pressures to censor or remove objectionable or infringing content they host. While decentralized providers can enable censorship-resistant storage, centralized content providers remain popular for performance and usability reasons. But centralized content providers can always choose not to respond to requests for a specific file, making it difficul...
متن کاملLavinia: An Audit-Payment Protocol for Censorship-Resistant Storage
As distributed storage systems grow in popularity, there is now a demand for a reliable incentive and payment system to guarantee and reward the pristine storage of documents. However, many existing proof-of-retrieval and micropayment protocols are not secure in a censorship resistance setting, in which powerful adversaries may infiltrate a system or coerce the original publisher to remove cont...
متن کاملCensorship resistant overlay publishing
The fundamental requirement of censorship resistance is content availability and discoverability — it should be easy for users to find and access documents. At the same time, participating storage providers should be unaware of what they are storing to preserve plausible deniability. Fulfilling these requirements simultaneously seems impossible — how does a system maintain a searchable index of...
متن کاملAn Analysis of GNUnet and the Implications for Anonymous, Censorship-Resistant Networks
Peer-to-peer networks are a popular platform for file sharing, but only few of them offer strong anonymity to their users. GNUnet is a new peer-to-peer network that claims to provide practical anonymous and censorship-resistant file sharing. In this paper we show that GNUnet’s performance-enhancing features can be exploited to determine the initiator of a download. We also present an efficient ...
