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

How much anonymity does network latency leak Low-latency anonymity systems such as Tor, AN.ON, Crowds, and 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 browsing and remote login. One consequence of these goals is that PriFi: A Traffic-Analysis-Resistant and Low-Latency 2019-1-18 · and low latency within the local network.

Popular anonymity protocols such as Tor provide low communication latency but are vulnerable to traffic-analysis attacks that can de-anonymize users.

In Next Generation Networks, Kerberos is becoming a key component to support authentication and key distribution for Internet application services. However, for this purpose, Kerberos needs to rectify certain deficiencies, especially in the area of privacy, which allow an eavesdropper to obtain information of the services users are accessing. This paper presents a comprehensive privacy

However, the user anonymity of these systems may be compromised by traffic analysis attacks as shown in [8, 2, 3, 10]. Such traffic analysis attacks can be either passive or active. A passive adversary can monitor the traffic pattern Anonymity Trilemma: Strong Anonymity, Low Bandwidth

churn, i.e., clients joining or leaving the network. Unlike other anonymity networks, the disconnection of any client invali-dates the current communication and forces re-transmission of the data. This is due to the design of the protocol: in the Low Latency «

Among the deployed low-latency anonymous networks, [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!)

Lower-Latency Anonymity - TU Wien 2015-2-20 · Low-Latency Anonymity Systems In contrast to high-latency systems, which attempt to distort timing patterns, low-latency systems like Crowds [9], Freedom [10], and The Onion Router (Tor) [11] are able to provide higher speed by actively seeking to limit processing delay and bandwidth overhead.
