Vuvuzela, a next-generation anonymity tool that protects users by adding noise

Tor allows users to browse the web anonymously, but has come under sustained attack – and cracks have begun to show. Is it time for a replacement? Vuvuzela, a prototype anonymising software designed by MIT researchers, is one attempt.

Vuvuzela works by encrypting as much metadata as possible, but (like its namesake) it also adds a lot of noise – fake messages with which to confuse attackers. As they are indistinguishable from genuine messages, this drowns out patterns of genuine communication that might otherwise compromise a user’s anonymity.
