Workshop on Anonymous Digital Signatures: Mechanisms & Usages

A workshop on Anonymous Digital Signatures: Mechanisms & Usages will be held as part of Trust 2010, the 3rd International Conference on Trust and Trustworthy Computing. The organizers are soliciting presentations to be presented in the workshop.

Anonymous digital signature is a fundamental cryptographic building block for providing privacy in the digital world. It can be used for anonymous authentication of Internet transactions and anonymous attestation of hardware platforms, with wide applications in trusted computing, e-commerce, content protection, and identity cards. Several research activities have focused on designing anonymous digital signature mechanisms (e.g. group signatures, direct anonymous attestation, and ring signatures). Different mechanisms have different security requirements and revocation models. Some of these mechanisms have been standardized and adopted by the computing industry. The Anonymous Digital Signatures: Mechanisms & Usages workshop is intended to encourage the development of new anonymous digital signature schemes and wider industry adoption of anonymous signatures.

Any topic which addresses the issues of anonymous digital signatures is a candidate for submission. Examples include, but are not limited to

  • Anonymous signature mechanisms
  • Revocation models and infrastructures for supporting anonymous signatures
  • Applications and usages of anonymous signatures

In addition to the call for presentation, this workshop will have invited speakers from industry and academia to share their experiences in designing and developing mechanisms and infrastructures for anonymous signatures. We will publish the presentation slides on the workshop webpage.

Invited Speakers:

Ronny Bjones
Senior Architect, Microsoft
Title: A Microsoft perspective on anonymous credentials

Ronny Bjones currently is working for Microsoft Corporate as senior architect in the identity & security division. Ronny joined Microsoft in 2002 to contribute in trustworthy computing. Later he became the EMEA security lead for Microsoft's enterprise business.He has 27 years of experience in ICT, 21 of those in security.Ronny published QuEST together with several industry specialists in the subject of electronic signatures. The book is a comprehensive guide on how to implement Electronic Signatures solutions and can be downloaded from microsoft.com. Ronny also co-authored "Best Practice for Applications using the electronic Identity Card".

Ronny oversees the whole areas of security but has a special interest in smart cards, PKI, Identity Metasystem, cryptography and digital signatures. Ronny is a board member of EEMA, an organisation providing guidance on e-Business. Ronny is also member of the ISSE program committee. He is also member of the OASIS Security Conference program committee and the World-eID program committee.

Since '89 he is active in the field of Information Security doing large projects for the European Central banks, Police forces, big financial institutes, European Commission, etc. Ronny Bjones was one of the four founders of Utimaco Belgium, where he worked ten years as R&D director. Before Utimaco Ronny worked for a Belgian EFT specialist called Prodata and one of the first firms to specialize in cryptography in Europe called Cryptech. Ronny Bjones is an active speaker on conferences. Ronny holds a bachelor in electronics, Master in IT management and MSc in Information technology.

 

Xavier Boyen
Professor, University of Liege, Belgium
Title: to be announced

Prof. Xavier Boyen received his Ph.D. from Stanford University in 2003. For about a decade, he has held various roles at Silicon Valley start-ups, most recently that of Chief Cryptographer at Voltage Security Inc. A couple of years ago, he turned to academia to take a Research Associate position at Stanford University. He recently joined the Montefiore Institute at the University of Liege, where he is now Professor of Computer Science, chair of Information Security and Cryptography. His research interests touch many areas of mathematical security, directed at the creation of cryptographic schemes that can truly benefit people collectively and individually. He has authored influential research papers, and some of his designs have seen large-scale deployments in industry and government.

 

Jan Camenisch
Research Staff Member, IBM Research in Zurich
Title: Anonymous Authentication: From Theory into Practice

Dr. Jan Camenisch received the Diploma in Electrical Engineering Science at ETH Zurich in 1993 and a Ph.D. in Computer Science ETH Zurich in 1998 ("Group Signatures Schemes and Payment Systems Based on the Discrete Logarithm Problems"). From 1998 till 1999 he has been Research Assistant Professor in Computer Science at the University of Aarhus, Denmark. Since 1999 he is Research Staff Member and project leader at IBM Research in Zurich. He is currently also the technical leader of the EU-funded project PrimeLife (www.primelife.eu) that aims at making privacy enhancing identities a reality.

His research interests are: cryptographic protocols, in particular those supporting privacy and anonymity; practical secure distributed computation. He has published over 70 refereed papers in these areas.
