Breaking an Efficient Anonymous Channel

by Birgit Pfitzmann - In EUROCRYPT , 1995
"... . At Eurocrypt 1993, Park, Itoh, and Kurosawa presented an "all/nothing election scheme and anonymous channel". The schemes are based on the mix-net and the election scheme constructed from this anonymous channel (Chaum 1981). One of the two main improvements is that the messages sent by n ..."

Fault Tolerant Anonymous Channel

by Wakaha Ogata, Kaoru Kurosawa, Kazue Sako, Kazunori Takatani , 1997
"... . Previous anonymous channels, called MIX nets, do not work if one center stops. This paper shows new anonymous channels which allow less than a half of faulty centers. A fault tolerant multivalued election scheme is obtained automatically. A very efficient ZKIP for the centers is also presented. 1 ..."

Quasi-anonymous channels

by Ira S. Moskowitz, Richard E. Newman, Paul F. Syverson - IN: IASTED CNIS , 2003
"... Although both anonymity and covert channels are part of the larger topic of information hiding, there also exists an intrinsic linkage between anonymity and covert channels. This linkage was illustrated in [1]; however, [1] just scratched the surface of the interplay between covert channels and anon ..."

The dangers of composing anonymous channels

by George Danezis, Emilia Käsper
"... Abstract. We present traffic analyses of two anonymous communications schemes that build on the classic Crowds/Hordes protocols. The AJSS10 [1] scheme combines multiple Crowds-like forward channels with a Hordes reply channel in an attempt to offer robustness in a mobile environment. We show that th ..."

Indistinguishability-based Characterization of Anonymous Channels

by Alejandro Hevia, Daniele Micciancio - IN PROC. OF PRIVACY ENHANCING TECHNOLOGIES WORKSHOP – PET ’ 08, VOLUME 5??? OF LNCS , 2008
"... We revisit the problem of anonymous communication, in which users wish to send messages to each other without revealing their identities. We propose a novel framework to organize and compare anonymity definitions. In this framework, we present simple and practical definitions for anonymous channels ..."

Anonymous Channel and Authentication in Wireless Communications

by W. -s. Juang, C.-L. Lei, C. -y. Chang - Comput. Commun , 1999
"... In this paper, we propose a scheme for providing anonymous channel service in wireless communications. By this service, many interesting applications, such as electronic elections, anonymous group discussions, with user identification confidential can be easily realized. No one can trace a sender&ap ..."

A Wireless-based Authentication and Anonymous Channels for GSM System

by Ren-junn Hwang, Jing-feng Li, Yu-kai Hsiao
"... Abstract. For mobile roaming environment, the mobile uses visiting network’s services, the mobile station and the visiting network must authenticate each other. We propose a new authentication and anonymous channels protocol for roaming mobile communication. Our scheme can securely apply to GSM and ..."

"... Abstract The authentication and anonymous channel protocol for large-scale area in wireless communications proposed in [Proc. Sixth IEEE Symposium on Computers and Communications (ISCCÕ01), 3-5 (2001) 36] by Lin-Jan is analyzed, proving that it is not secure. More precisely, fake anonymous channel ..."
