Censorship is a critical threat to freedom of expression, belief, and thought around the world. Luckily, many people are building technologies that attempt to undermine the efforts of oppressive regimes around the world. These technologies allow people to circumvent any censorship of their internet usage. The Tor network is one of the primary methods of doing so. It is an overlay, peer-to-peer, anonymization network that encrypts internet traffic. Sadly, access to this network is censored heavily in countries like China, Russia, and Iran. Salmon is one of the many papers that propose solutions to this problem; specifically the problem of bridge proxy distribution, which aims to distribute hidden proxies robustly to censored users in order to access Tor without getting blocked by the censor.
