Telex is a new approach to circumventing state-level Internet censorship. It allows a user to circumvent a censor without alerting the censor to the act of circumvention. Telex operates in the network infrastructure at any ISP between the censors network and non-blocked portions of the Internet rather than at network end points. It complements anonymizing services like Tor like Tor, which focus on hiding with whom the user is attempting to communicate instead of that user is trying to have an anonymous conversation. With Telex users dont need to know any secrets to connect.”]
