We investigate the Internet on a global scale, examining the infrastructure that allows us all to communicate and developing techniques to stop the next generation of adversaries.
We develop systems to allow anonymous and robust communication even under the surveillance of powerful governments and while enduring adverse network conditions.
We study the implications of censorship and privacy in the digital world and seek to develop new techniques to advance the efforts towards a more free and open Internet.
