Local View Attack on Anonymous Communication
نویسندگان
چکیده
We consider anonymous communication protocols based on onions: each message is sent in an encrypted form through a path chosen at random by its sender, and the message is re-coded by each server on the path. Recently, it has been shown that if the anonymous paths are long enough, then the protocols provide provable security for some adversary models. However, it was assumed that all users choose intermediate servers uniformly at random from the same set

A Stealthy Attack Against Tor Guard Selection
Tor is a popular low-latency anonymous communication system which could provide anonymity and anti-censorship. Based on previous researches on de-anonymization of Tor, this paper proposes a novel approach to attack users’ guard selection which can pose great threat against Tor users' anonymity. Under the current design of Tor, once entry guards are compromised, the probability that an attacker ...
متن کاملNovel Approach To Cell-Counting-Based Attack Against Tor
Different low-latency unidentified communication systems such as Tor and Anonymizer have been deliberate to make available anonymity service for users. In order to hide from view the communication of users, most of the secrecy systems pack the application data into equal-sized cells. Through extensive experiments on Tor, we originate that the size of IP packets in the Tor network can be very ac...
متن کاملPrivacy and Anonymity in Mobile Ad Hoc Networks
Providing privacy is often considered a keystone factor for the ultimate take up and success of mobile ad hoc networking. Privacy can best be protected by enabling anonymous communication and, therefore, this chapter surveys existing anonymous communication mechanisms for mobile ad hoc networks. On the basis of the survey, we conclude that many open research challenges remain regarding anonymit...
متن کاملAttacking Anonymous Web Browsing at Local Area Networks Through Browsing Dynamics
The majority of current anonymous systems focus on improving anonymity at the network and website level in order to defend against traffic analysis attacks. However, the vulnerability of the connections between end users and the anonymous network do not attract any attention yet. For the first time, we reveal an end user browsing dynamics based attack on anonymous browsing systems at the LAN wh...
