HoneyBadgerMPC and AsynchroMix: Practical AsynchronousMPC and its Application to Anonymous Communication
multiparty computation robustness
2019/8/2
Multiparty computation as a service (MPSaaS) is a promising approach for building privacy-preserving communication systems.However, in this paper, we argue that existing MPC implementations are inadeq...
Simple and Efficient Approach for Achieving End-to-End Anonymous Communication
cryptographic protocols Anonymous communication
2019/7/15
Anonymous communication, that is secure end-to-end and unlinkable, plays a critical role in protecting user privacy by preventing service providers from using message metadata to discover communicatio...
CoverUp: Privacy Through "Forced" Participation in Anonymous Communication Networks
anonymous communication privacy enhancing technologies
2017/3/6
The privacy guarantees of anonymous communication networks (ACNs) are bounded by the number of participants. As a consequence, an ACN can only achieve strong privacy guarantees if it succeeds in attra...
AnoA: A Framework For Analyzing Anonymous Communication Protocols
Anonymous Communication Anonymity Metric Relationship Anonymity
2016/1/26
Anonymous communication (AC) protocols such as the widely used Tor network have been designed to
provide anonymity over the Internet to their participating users. While AC protocols have been the sub...
We ask whether it is possible to anonymously communicate a large amount of data using
only public (non-anonymous) communication together with a small anonymous channel. We think this
is a central qu...
TUC: Time-sensitive and Modular Analysis of Anonymous Communication
cryptographic protocols security analysis of protocols
2014/3/7
The anonymous communication protocol Tor constitutes the most widely deployed technology for providing anonymity for user communication over the Internet. Several frameworks have been proposed that sh...
In this research report we present an UC framework for the general task of anonymous communication. Definition of the ideal and the real models are carried out in the BPW (Backes-Pfitzmann-Waidner) fo...

2010/2/1
Security and efficiency are two crucial issues in vehicular ad hoc networks.
Many researches have devoted to these issues. However, we found that most of the
proposed protocols in this area are inse...
