CENO IS A PEER-TO-PEER CENSORSHIP CIRCUMVENTION SYSTEM DESIGNED FOR ACCESSING WEBSITES FROM THE STRICTEST INTERNET ENVIRONMENTS. CENO BRIDGES AN ANONYMOUS DARKNET WITH THE WEB.
Receives a website request from the user and communicates it to Transport. Displays received website content
Retrieves a website and bundles all elements for Storage in Freenet
Secure and anonymous cache for bundled websites, distributed on Freenet nodes
Communications between CeNo components on Freenet. Requests websites from Edges and bundles from Storage. Delivers to Client
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.
Using a public key infrastructure, all content is encrypted during transit and at rest
Every file is uniquely encrypted and the keys distributed on the network. A node cannot know what information it is storing for the network
No one knows which content a node is requesting or storing. Its impossible to link a node on the network to an IP address
