Publications

Recent publications from the Censored Planet and related projects.

Our research community is a vibrant and growing subfield that exists at the intersection of networking, security and privacy, Internet measurement, and social and political science. Our major publication venues include systems security and privacy conferences (USENIX Security, IEEE S&P, ACM CCS, NDSS, PETS, and SIGCOMM) and measurement conferences (ACM IMC), as well as more specialized interdisciplinary workshops (USENIX FOCI).

Presented in reverse chronological order.
