Design principles for low latency anonymous network

Design principles for low latency anonymous network 2018-4-18 · Design principles for low latency anonymous network systems secure against timing attacks Abstract Low latency anonymous network systems, such as Tor, were consideredsecureagainst timing attacks when the threat model does not include a global ad- versary. In this threat model the adversary can only see part of the links in the system. The U.S. National Security Agency (NSA) has called Tor "the king of high-secure, low-latency Internet anonymity", and BusinessWeek magazine has described it as "perhaps the most effective means of defeating the online surveillance efforts of intelligence agencies around the world". PriFi: Low-Latency Anonymity for Organizational Networks - NASA/ADS Organizational networks are vulnerable to traffic-analysis attacks that enable adversaries to infer sensitive information from the network traffic - even if encryption is used.

Tor Anonymity Network & Traffic Analysis

Aug 30, 2006 · Abstract. We introduce mix rings, a novel peer-to-peer mixnet architecture for anonymity that yields low-latency networking compared to existing mixnet architectures.A mix ring is a cycle of continuous-time mixes that uses carefully coordinated cover traffic and a simple fan-out mechanism to protect the initiator from timing analysis attacks.

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.

Abstract—Low latency anonymity systems, like Tor and I2P, support private online communications, but offer lim-ited protection against powerful adversaries with widespread eavesdropping capabilities. It is known that general-purpose communications, such as web and file transfer, are difficult to protect in that setting. Aug 30, 2006 · Abstract.

[5], [6]. Research on flow-based anonymity applications has been active in recent years to preserve anonymity in low-latency applications, such as web browsing and peer-to-peer file sharing [7], [8]. Tor [8] is a popular low-latency anonymous communication network, supporting TCP applications on the Internet. At the
