Tor Adopts Counter Galois Onion Encryption to Reinforce Security
The Tor network is replacing its legacy relay encryption with Counter Galois Onion (CGO), a research-backed design that hardens Tor against tagging attacks, tampering and modern cryptanalytic threats. This analysis explains how Tor Galois onion encryption works, what changes for users and relay operators, and why it matters for long-term anonymity.
