How to achieve blocking resistance for existing systems enabling anonymous web surfing

Stefan K�psell, Ulf Hillig
2004 Proceedings of the 2004 ACM workshop on Privacy in the electronic society - WPES '04  
We are developing a blocking resistant, practical and usable system for anonymous web surfing.  ...  The proposed solution is an add-on to existing anonymity systems. First we give a classification of blocking criteria and some general countermeasures.  ...  For these reasons our goal is to develop a practical, usable and blocking resistant system for anonymous web surfing.  ...

Denial of Service: Another Example [chapter]

Jianxin Jeff Yan
2002 IFIP Advances in Information and Communication Technology  
The author is grateful to anonymous reviewers of ACM NSPW'OI (New Security Paradigm Workshop) and IFIP SEC2002 for their helpful comments.  ...  Dynamic DNS [14] enables different web servers with different IP addresses to share a single DNS name, and this technique is also useful for defending the blocking DoS attack.  ...  The Freedom network [6] enabled a user to anonymously browse websites with a nym, and it supported encrypted anonymous communication between a browser and a web server.  ...

Message in a bottle

Luca Invernizzi, Christopher Kruegel, Giovanni Vigna
2013 Proceedings of the 29th Annual Computer Security Applications Conference on - ACSAC '13  
We believe that, to achieve resilience to blocking, anti-censorship systems must abandon the idea of having a limited number of entry points.  ...  To block this system, censors are left with a needle-in-a-haystack problem: Unable to identify what bears hidden messages, they must block everything, effectively disconnecting their own network from a  ...  These systems focus on hiding the user identities from the websites they are surfing to. They have a low latency, which makes web surfing possible (which miab does not).  ...

On the risks of serving whenever you surf

Jon McLachlan, Nicholas Hopper
2009 Proceedings of the 8th ACM workshop on Privacy in the electronic society - WPES '09  
These shortcomings lead to an attack that can expose the IP address of bridge operators visiting certain web sites over Tor. We also discuss mitigation mechanisms.  ...  clients connected to a bridge interferes with traffic to and from the bridge operator.  ...  Acknowledgments We thank our shepherd, Steven Murdoch, for helpful suggestions regarding the presentation of our attack; Chris Arnold and Tim Stucki for sharing the results of their open proxy survey;  ...

Project "anonymity and unobservability in the Internet"

Oliver Berthold, Hannes Federrath, Marit Köhntopp
2000 Proceedings of the tenth conference on Computers, freedom and privacy challenging the assumptions - CFP '00  
It is a hard problem to achieve anonymity for real-time services in the Internet (e.g. Web access).  ...  However, some of the existing concepts enable an attacker to flood the system in order to separate a certain message. 5.  ...  During the last three years we developed several Mix-based and proxy-based anonymity services (for Web surfing and similar real-time services).  ...

Leveraging Internet Services to Evade Censorship [chapter]

Apostolis Zarras
2016 Lecture Notes in Computer Science  
To address this limitation of state-of-theart systems, we introduce Camouflage, an approach to combine multiple non-blocked communication protocols and dynamically switch among these tunnels.  ...  Each protocol is only used for a limited amount of time and the Internet connection is transparently routed through instances of different censorship circumvention systems.  ...  Thus, to show that a circumvention system must only be used for accessing censored web pages, and not for web surfing, we measured its performance.  ...

Towards Pseudonymous e-Commerce

Marc Rennhard, Sandro Rafaeli, Laurent Mathy, Bernhard Plattner, David Hutchison
2004 Electronic Commerce Research  
Current e-commerce practice enforces a customer to disclose her identity to the e-shop and the use of credit cards makes it straightforward for an e-shop to know the real identity of its customers.  ...  In this paper, we present novel components that enable secure pseudonymous e-commerce.  ...  The Freedom System [Boucher et al., 4] was a commercial service provided by Zeroknowledge Systems to enable users to browse the Web anonymously.  ...

To accurately detect search poisoning cases, we designed a novel detection system called SURF.  ...  Our evaluation on realworld search poisoning instances shows that SURF can achieve a detection rate of 99.1% at a false positive rate of 0.9%.  ...  At the same time, SURF can be deployed at each single client to detect (and block) poisoned search results.  ...
