People won't forget what you did when it was their turn in the hot seat, for good or ill. And everyone gets a turn in the hot seat.

Bootstrapping Communications into an Anti-Censorship System
2nd USENIX Workshop on Free and Open Communications on the Internet
Adversary-resistant communication bootstrapping is
a fundamental problem faced by many circumvention
(anti-censorship) systems such as Tor. Censoring regimes
actively harvest and block published Tor entry points and
bridge nodes. More recently, some countries have resorted
to reactive (follow-up) probing of the destination hosts
of outbound encrypted traffic to identify unpublished Tor
nodes. We present the design of a new architecture for
bypassing censorship, called…Adversary-resistant communication bootstrapping is
a fundamental problem faced by many circumvention
(anti-censorship) systems such as Tor. Censoring regimes
actively harvest and block published Tor entry points and
bridge nodes. More recently, some countries have resorted
to reactive (follow-up) probing of the destination hosts
of outbound encrypted traffic to identify unpublished Tor
nodes. We present the design of a new architecture for
bypassing censorship, called DEFIANCE, that extends
Tor with resilience to both active harvesting and network
scanning attacks. The first goal is accomplished using
the DEFIANCE Rendezvous Protocol (RP), and the second
is achieved using a novel handshake that we call
Address-Change Signaling (ACS). We describe prototype
implementations of both components, discuss the limits
of our architecture, and evaluate what it would take for
a determined adversary to defeat our system. While we
develop our prototype components over Tor, their design
can be easily extended to other circumvention systems.Other authors -
