## Reliable Anonymous Communication Evading Censors and Repressors (S28)
* 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 Georgetown University and 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).
* 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.
## Tor Browser Security, Performance, & Usability Improvements (S58)
* Build the infrastructure and processes to enable us to migrate Tor Browser for Android away from Fennec (on the Firefox Extended Support Release cycle) and onto Fenix (on the Firefox regular release cycle).
* Migrate Tor Browser for Android onto Fenix and away from Fennec.
## Expanding Research Frontiers with a Next-Generation Anonymous Communication Experimentation (ACE) Framework (S38)
* The goal of this project is to develop a scalable and mature deterministic network simulator, capable of quickly and accurately simulating large networks such as Tor

## Onion Services (S27) - FINISHED
* Enhance onion services and make v3 the default version on Core Tor, so it can scale and be more stable, with the goal of enabling more organizations to adopt it for their users.
* Improve the end user experience of onion services with the goal of increasing user adoption and retention.
* Research on the possible use of proof of work for defending against HS DoS attacks
## Walking Onions: Scaling & Saving Bandwidth on the Tor Network (S69)
* Implementation of the first phase of the Walking Onions proposal, a set of protocols improving scalability for the Tor network by enabling constant-size scaling of the information each user must download. Walking Onions will allow us to remove nearly all directory overhead from the Tor protocol, enabling Tor to scale to many more clients and relays, with no reduction in security.
