Tweeters Anonymous: Applying and Understanding Mix Networks & Onion Encryption for Anonymity

| 2:00pm to 3:30pm Virtual, via Microsoft Teams

Use of Tor and other tools for anonymity has risen in popularity since the NSA leaks in 2013-14, with many users opting to hide their location for a variety of reasons. One of the earliest proposed methods for anonymity is a mix network, which leverages onion encryption. In this SIG we'll explore a few core concepts of anonymity, walk through the mix network architecture and onion encryption, and finally cover a proof of concept app that leverages mixes in AWS to publish Tweets to a anonymous Twitter account while hiding location and obfuscating the connection between user and Tweet.
