Project Title: Reliable Anonymous Communication Evading Censors and Repressors (RACECAR)

Project Period: 3/1/2019 - 2/28/2023

Teams involved:

  • network
  • anti-censorship

Project Goals/Activities

1.1 Task 1: Obfuscated Channels Objective. To handle an adversary that observes and may control the entire network underlying RACE communications, we develop obfuscated channels in which communication is hidden within traffic generated by common applications. Working with external collaborators at the U.S. Naval Research Laboratory, this task develops a suite of obfuscated channels to support RACE goals for varying adversarial networks (i.e., deployment scenarios).

1.2 Task 2: Channel Integration and Analysis Objective. To develop tools for evaluating the performance and security of obfuscated channels at scale, both by themselves and when integrated with TA1 protocols. To apply those tools to RACECAR channels.
