STORAGE

Secure and anonymous cache for bundled websites, distributed on Freenet nodes

TRANSPORT

Communications between CeNo components on Freenet. Requests websites from Edges and bundles from Storage. Delivers to Client

WHY CENO?

Most circumvention systems end up playing cat-and-mouse with the censor - getting unblocked proxy servers to the user before the blocklists are updated. By design, peer-to-peer networks have an advantage with every participant acting as a proxy for someone else. The protocol can locate information anywhere on the network, without user knoweldge or intervention. CeNo is built on top of Freenet, an anonymous and highly encrypted network for file sharing and storage, designed for censorship resistance. CeNo allows users to request Web pages and store them inside the censored zone. Once a site is inserted into Freenet, it is accessible to every CeNo user. No further requests outside the censored zone are necessary.

SECURITY PROPERTIES

ENCRYPTED TRANSPORT AND STORAGE

Using a public key infrastructure, all content is encrypted during transit and at rest

PLAUSIBLE DENIABILITY

Every file is uniquely encrypted and the keys distributed on the network. A node cannot know what information it is storing for the network

COMPLETE ANONYMITY

No one knows which content a node is requesting or storing. Its impossible to link a node on the network to an IP address

CENO IS BUILT ON

GITHUB

This is an open source project, developed and hosted on GitHub. It will stay that way

FREENET

Since 2000, one of the largest anonymous publishing networks with an estimated 100k nodes

BUNDLER

A tool to transport websites as inlined static files, with confidentiality and integrity
