Showing Credentials Without Identification: SIgnatures Transferred Between Unconditionally Unlinkable Pseudonyms

The techniques presented allow powerful, readily extensible, and flexible arrangements for exchange of information between organizations about individuals. They protect against abuses by individuals,…

Novel security techniques for online systems

By ensuring entry to subsystems (zones) with different facilities and security levels, log-in procedures can do more than simply delay illicit access.

Privacy and Identity Management for Life

At the end of the PrimeLife EU project, a book will contain the main research results. It will address primarily researchers. In addition to fundamental research it will contain description of best…

A formal approach toward authenticated authorization without identification

A formal approach toward authenticated authorization without identification is proposed for the first time in this context.

Anonymity and Security Support for Persistent Enterprise Conversation

This paper proposes an anonymous and secure conversation protocol based on a concept of alias certificate with analysis to show that the scheme satisfies such requirements.

A Risk Driven Approach to Designing Privacy Enhanced Secure

In the context of authorization in distributed systems, security and privacy often seem at odds; the need to identify misbehaving users calls for either identity-based authorization or identity escrow allowing re-identification of users.

Threats and countermeasures for network security

In the late 1980's, the traditional threat of anonymous break-ins to networked computers was joined by viruses and worms, multiplicative surrogates that carry out the bidding of their authors.…

A Cryptographic Framework for the Controlled Release of Certified Data

This talk is actually about what cryptographics can do for mass protection and real world cryptographic techniques to control the release of certified data.

Attribute-based identity management : [bridging the cryptographic design of ABCs with the real world]

This thesis focusses on the cryptographic and broader technical challenges of applying ABCs in identity management, both online and offline.

A Non-Iterative Electronic Cash System

The first electronic cash system whose transactions require no interaction between the parties is given, based on the computational intractability of factoring Blum integers.

New directions in cryptography

This paper suggests ways to solve currently open problems in cryptography, and discusses how the theories of communication and computation are beginning to provide the tools to solve cryptographic problems of long standing.

A method for obtaining digital signatures and public-key cryptosystems

An encryption method is presented with the novel property that publicly revealing an encryption key does not thereby reveal the corresponding decryption key, soriers or other secure means are not needed to transmit keys.
