2010-3-6 · Low-latency anonymity systems such as Tor, AN.ON, Crowds, and Anonymizer.com aim to provide anonymous connections that are both untraceable by “local” adversaries who control only a few machines and have low enough delay to support anonymous use of network services like Web

Popular anonymity protocols such as Tor provide low communication latency but are vulnerable to traffic-analysis attacks that can de-anonymize users. On the Effectiveness of Low Latency Anonymous Network … 2009-4-4 · the adversary is passive. Among the deployed low-latency anonymous networks, anonymizer.com [3] is the most pop-ular commercial anonymous communication service in the USA and Tor [10] is the most popular open source low-latency anonymous network. To exploit the timing constraint of the low-latency anonymous networks, a number of timing attacks Theory and Design of Low-latency Anonymity Systems 2010-10-19 · Anonymity network Bob watch (or be!) Bob! watch Alice! Control part of the network! Etc, etc. 14 Anonymity isn't confidentiality: • Not the first distributed low-latency anonymity system. • Introduced about a year after the first onion routing deployment, and two years after Anonymizer.

Low-latency anonymous communication networks require padding to resist timing analysis attacks, and dependent link padding has been proven to prevent these attacks with minimal overhead. In this paper we consider low-latency anonymity networks that implement dependent link padding, and examine various network topologies.
and the largest deployed anonymity network, Tor [6], has attracted an estimated 250000 users. Many network services, such as web-browsing or online chat, require low-latency communication to remain usable. Low-latency anonymous communica-tion networks are vulnerable to timing analysis, which can be performed by a
2013-5-3 · Abstract. Tor is the most popular low-latency anonymity network for enhanc-ing ordinary users’ online privacy and resisting censorship. While it has grown in popularity, Tor has a variety of performance problems that result in poor quality of service, a strong disincentive to use the system, and weaker anonymity prop-erties for all users. Stealthy Traffic Analysis of Low-Latency Anonymous 2013-7-24 · compromise) only a fraction of the network. A typical goal for low-latency systems is to ensure that an adversary who observes or controls a fraction f of the network can com-promise the anonymity of f2 of the flows. The hope is that making f large would require a high resource expenditure, COMPARATIVE ANALYSIS OF LOW LATENCY …
