Tor
The Tor Project est un réseau d'anonymat distribué qui achemine le trafic internet via un système de relais bénévoles utilisant un chiffrement multicouche pour dissimuler l'identité et la localisation de l'utilisateur.
Le système fournit des outils pour le contournement de la censure réseau, utilisant des ponts et des transports enfichables pour contourner les blocages internet et obscurcir les modèles de trafic. Il permet également l'hébergement de services onion, permettant aux sites web et services d'être publiés de telle sorte qu'ils ne soient accessibles que via le réseau, dissimulant la localisation physique du serveur.
Le projet couvre des capacités plus larges de confidentialité et d'infrastructure, y compris la protection contre le fingerprinting du navigateur pour empêcher le suivi via la configuration logicielle et l'isolation de session pour bloquer les trackers tiers. Il prend également en charge l'exploitation de relais bénévoles pour augmenter la capacité totale et la résilience du réseau de trafic chiffré.
Features
- Anonymity Network Routing - Transmits network data through a distributed system of volunteer nodes to hide the connection between user and destination.
- Layered Encryption Circuits - Implements onion-style layered encryption where data is wrapped in multiple layers and peeled away by each relay node.
- Censorship Circumvention - Provides tools and protocols specifically designed to bypass internet filters and network restrictions by masking traffic identity.
- Distributed Anonymity Relays - Routes traffic through a chain of volunteer nodes to decouple the source identity from the destination address.
- Fingerprint Mitigation Tools - Hides unique software characteristics and isolates sessions to stop websites from tracking users via browser configuration.
- Browser Fingerprint Spoofing - Hides unique browser characteristics using technical protections to stop websites from tracking users based on their software configuration.
- Pluggable Transports - Transforms network traffic patterns into different protocols to bypass deep packet inspection and censorship filters.
- Privacy Browsing Tools - Hides the destination of internet traffic from network monitors to prevent observers from determining which websites are being visited.
- Onion - Enables the publishing of websites and services reachable only through the Tor network to conceal server locations.
- Fixed-Size Cell Transmission - Fragments network traffic into fixed-size encrypted cells to prevent traffic analysis based on packet size.
- Volunteer Relay Operations - Running a network node to carry encrypted traffic, increasing the overall capacity and resilience of the distributed network.
- Randomized Circuit Selection - Randomly selects a sequence of nodes to build a temporary tunnel for transmitting data streams.
- Rendezvous Point Discovery - Connects clients to hidden services by meeting at a neutral third party node to hide both identities.
- Anonymous Traffic Relays - A volunteer node that carries encrypted data to increase the total capacity and resilience of the anonymity network.
- Volunteer Relay Operations - Supports the operation of volunteer relays to increase the total capacity and resilience of the network.
- Directory Consensus Mechanisms - Distributes a signed list of available relays and their status to all clients via a trusted set of authorities.
- Anti-Tracking Session Isolations - Prevents third-party trackers from following users by isolating sessions and automatically clearing cookies and browsing history.
