Threat Modeling and Circumvention of Internet Censorship by David Fifield
Threat modeling and circumvention of Internet censorship By David Fifield A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate Division of the University of California, Berkeley Committee in charge: Professor J.D. Tygar, Chair Professor Deirdre Mulligan Professor Vern Paxson Fall 2017 1 Abstract Threat modeling and circumvention of Internet censorship by David Fifield Doctor of Philosophy in Computer Science University of California, Berkeley Professor J.D. Tygar, Chair Research on Internet censorship is hampered by poor models of censor behavior. Censor models guide the development of circumvention systems, so it is important to get them right. A censor model should be understood not just as a set of capabilities|such as the ability to monitor network traffic—but as a set of priorities constrained by resource limitations. My research addresses the twin themes of modeling and circumvention. With a grounding in empirical research, I build up an abstract model of the circumvention problem and examine how to adapt it to concrete censorship challenges. I describe the results of experiments on censors that probe their strengths and weaknesses; specifically, on the subject of active probing to discover proxy servers, and on delays in their reaction to changes in circumvention. I present two circumvention designs: domain fronting, which derives its resistance to blocking from the censor's reluctance to block other useful services; and Snowflake, based on quickly changing peer-to-peer proxy servers. I hope to change the perception that the circumvention problem is a cat-and-mouse game that affords only incremental and temporary advancements. -

Cloudtransport: Using Cloud Storage for Censorship-Resistant Networking
CloudTransport: Using Cloud Storage for Censorship-Resistant Networking Chad Brubaker1,2, Amir Houmansadr2, and Vitaly Shmatikov2 1 Google 2 The University of Texas at Austin Abstract. Censorship circumvention systems such as Tor are highly vulnerable to network-level filtering. Because the traffic generated by these systems is disjoint from normal network traffic, it is easy to recog- nize and block, and once the censors identify network servers (e.g., Tor bridges) assisting in circumvention, they can locate all of their users. CloudTransport is a new censorship-resistant communication system that hides users’ network traffic by tunneling it through a cloud storage ser- vice such as Amazon S3. The goal of CloudTransport is to increase the censors’ economic and social costs by forcing them to use more expen- sive forms of network filtering, such as large-scale traffic analysis, or else risk disrupting normal cloud-based services and thus causing collateral damage even to the users who are not engaging in circumvention. Cloud- Transport’s novel passive-rendezvous protocol ensures that there are no direct connections between a CloudTransport client and a CloudTrans- port bridge. Therefore, even if the censors identify a CloudTransport connection or the IP address of a CloudTransport bridge, this does not help them block the bridge or identify other connections. CloudTransport can be used as a standalone service, a gateway to an anonymity network like Tor, or a pluggable transport for Tor. It does not require any modifications to the existing cloud storage, is compatible with multiple cloud providers, and hides the user’s Internet destinations even if the provider is compromised. -
A Privacy Threat for Internet Users in Internet-Censoring Countries
A Privacy Threat for Internet Users in Internet-censoring Countries Feno Heriniaina R. College of Computer Science, Chongqing University, Chongqing, China Keywords: Censorship, Human Computer Interaction, Privacy, Virtual Private Networks. Abstract: Online surveillance has been increasingly used by different governments to control the spread of information on the Internet. The magnitude of this activity differs widely and is based primarily on the areas that are deemed, by the state, to be critical. Aside from the use of keywords and the complete domain name filtering technologies, Internet censorship can sometimes even use the total blocking of IP addresses to censor content. Despite the advances, in terms of technology used for Internet censorship, there are also different types of circumvention tools that are available to the general public. In this paper, we report the results of our investigation on how migrants who previously had access to the open Internet behave toward Internet censorship when subjected to it. Four hundred and thirty-two (432) international students took part in the study that lasted two years. We identified the most common circumvention tools that are utilized by the foreign students in China. We investigated the usability of these tools and monitored the way in which they are used. We identified a behaviour-based privacy threat that puts the users of circumvention tools at risk while they live in an Internet-censoring country. We also recommend the use of a user-oriented filtering method, which should be considered as part of the censoring system, as it enhances the performance of the screening process and recognizes the real needs of its users. -
Vyprvpn Auf Einem ASUS Router Einrichten “Schritt Für Schritt”
8.11.2019 Anleitung: ASUS Router mit VPN in Betrieb nehmen "Schritt für Schritt" mit VyprVPN - dem besten VPN-Service für sicheres Sufen Menue Anleitung: VyprVPN auf einem ASUS Router einrichten “Schritt für Schritt” von Markus Hanf Letzte Aktualisierung: 12. September 2019 Approbierter Mathematiker und Netzwerkspezialist. Dozent an einigen Universitäten. Es ist ganz einfach einen ASUS Router direkt in Betrieb zu nehmen, ganz unabhängig davon welchen Internetrouter Du derzeit verwendest. Wir haben einen ganzen Vorgang der Inbetriebnahme in einer Anleitung beschrieben. VPN Router Schematische Darstellung Einen VPN-Service direkt über den ASUS Router zu verwenden bietet die folgenden Vorteile: Alle Geräte (auch SmartTV, FireTV, AndroidTV, xBox usw) werden zuverlässig über VPN verbunden ohne Softwareinstallation. Die Firewall und die zusätzlichen Schutzfunktionen die im Router vorhanden sind lassen es zu, auch Kinder und Jugendliche vor Bedrohungen aus dem Internet zu schützen. (Malwareschutz, Sperren von Webseiten, Zugriff für bestimmte Apps auf Smartphones usw) Die gesamte Familie wird zuverlässig vor Abmahnungen und sonstigen Fallen im Internet geschützt, ohne dass dabei Software oder Apps auf den Geräten zusätzlich installiert werden müssen. Die Benutzer des Routers werden “Anonymisiert” und nutzen damit eine nicht direkt zuordenbare Internetadresse für alle täglichen Aktivitäten. Zuverlässiger Schutz aller Nutzer vor Überwachung und Vorratsdatenspeicherung und damit auch eine aktive Maßnahme für eine bessere Privatsphäre. Hilfe & Beratung -

The Impact of Media Censorship: Evidence from a Field Experiment in China
The Impact of Media Censorship: Evidence from a Field Experiment in China Yuyu Chen David Y. Yang* January 4, 2018 — JOB MARKET PAPER — — CLICK HERE FOR LATEST VERSION — Abstract Media censorship is a hallmark of authoritarian regimes. We conduct a field experiment in China to measure the effects of providing citizens with access to an uncensored Internet. We track subjects’ me- dia consumption, beliefs regarding the media, economic beliefs, political attitudes, and behaviors over 18 months. We find four main results: (i) free access alone does not induce subjects to acquire politically sen- sitive information; (ii) temporary encouragement leads to a persistent increase in acquisition, indicating that demand is not permanently low; (iii) acquisition brings broad, substantial, and persistent changes to knowledge, beliefs, attitudes, and intended behaviors; and (iv) social transmission of information is statis- tically significant but small in magnitude. We calibrate a simple model to show that the combination of low demand for uncensored information and the moderate social transmission means China’s censorship apparatus may remain robust to a large number of citizens receiving access to an uncensored Internet.
