  Recent initiatives known as Future Internet Architectures (FIAs) seek to
redesign the Internet to improve performance, scalability, and security.
However, some governments perceive Internet access as a threat to their
political standing and engage in widespread network surveillance and
censorship. In this paper, we provide an in-depth analysis into the designs of
prominent FIAs, to help understand of how FIAs impact surveillance and
censorship abilities. Then, we survey the applicability of privacy-enhancing
technologies to FIAs. We conclude by providing guidelines for future research
into novel FIA-based privacy-enhancing technologies, and recommendations to
guide the evaluation of these technologies.
