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 « 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 Drawing on our experiences deploying Tor (the second-generation onion routing network), we describe social challenges and technical issues that must be faced in building, deploying, and sustaining a scalable, distributed, low-latency anonymity network.

NRL Publication Release Number: 05-1226-0990 Low-latency anonymity systems like Tor are designed to provide support for applications like Web browsing, video streaming, and online chat. To make the commutation between source and destination unlinkable, Tor routes all the traffic through three Tor relays, which are spread across the globe.
On the Effectiveness of Trafﬁc Analysis Against Anonymity
Abstract. 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 browsing and remote login.

We conﬁrm the trilemma that an AC protocol can only achieve two out of the following three properties: strong anonymity (i.e., anonymity up to a negligible chance), low bandwidth overhead, and low latency overhead.

Anonymity Trilemma: Strong Anonymity, Low Bandwidth Overhead, Low Latency - Choose Two Abstract: This work investigates the fundamental constraints of anonymous communication (AC) protocols. We analyze the relationship between bandwidth overhead, latency overhead, and sender anonymity or recipient anonymity against the global passive (network
