Tor, initially developed by the U.S. Naval Research Laboratory, has evolved into a globally recognized platform for anonymous internet browsing. Since 2006, the Tor Project, a non-profit organization, has been responsible for its continued development. With 85% of funding from U.S. government agencies and the rest from private and NGO contributions, the Tor Project’s mission is to provide a secure and free solution for anonymizing internet traffic.
Tor, short for “The Onion Router,” operates by routing users’ data through three random servers, or nodes, which form layers like an onion. This ensures that the original IP address remains hidden, and the website being accessed only sees the exit node’s IP. Every 10 minutes, the connection changes to different nodes, further enhancing anonymity. The data within the Tor network is encrypted, but once it reaches the exit node, it’s decrypted, meaning users should always employ encryption (like HTTPS) for sensitive communication.
Tor is not without vulnerabilities. The exit nodes—run by volunteers and organizations—have the potential to expose data if not encrypted. Moreover, entities with significant control over internet infrastructure or large numbers of infected Tor nodes could potentially identify users through statistical analysis. However, with 6,500 active servers and millions of daily users, Tor remains a vital tool for those seeking privacy, especially in countries with strict surveillance. The darknet, known for its anonymity, relies on Tor for access to its hidden services and forums, accessible only via the Tor browser.
