Introduction to the ABC4Trust Project and Privacy-ABCs–Rapid growth of communication infrastructures and enterprise software solutions has caused electronic services to penetrate into our everyday life. So it is not far from reality that many personal and trust-sensitive transactions happen online. In this regard, one of the biggest challenges to deal with will be proper user authentication and access control, as strong authentication and authorization techniques used nowadays are double-edged swords: while they can protect service providers by offering a satisfactory level of resilience against unauthorized accesses, most of these technologies have the drawback of threatening the clients' privacy. In this presentation, we will give an overview of the privacy problems of  the existing Identity Management Systems and then open the discussion on the ABC4Trust project that focuses on  Privacy-preserving Attribute-based Credentials to address  the shortcomings of the existing IdMs.

 

Souheil Bcheri is the founder of the Swedish company Eurodocs AB. He has a Master Degree in Mathematics, Statistics and Computer Sciences. Souheil has been working for more than 20 years within the sectors large data analysis and IT-security, including digital identification, encryption and digital signatures. Furthermore, Souheil is very experienced in working on projects dealing with identity, anonymity, and privacy protection.

Privacy-preserving School Communication for Pupils; The Swedish School Pilot - Social networks have become widely used nowadays and are increasingly finding acceptance in different scenarios of our daily activities. Depending on the type of the users being targeted, social networks have been set up to better serve users, enhance their online experience and provide them with an easy way to interact and share with the other members of the network. In this session we are going to describe the members of the use case community – pupils of a Swedish school, their guardians and teachers – were able to use the provided “community services” while, at the same time their privacy was protected by enabling pseudonymous and anonymous access.








Yannis Stamatiou graduated from the University of Patras, Department of Computer Engineering and Informatics. He is currently Associate Professor at the Department of Business Administration of the University of Patras, Greece and Consultant (with deputy directorresponsibilities) on Cryptography and Security for the Security Sector of the Computer Technology Institute & Press (“Diophantus”) in Patras, Greece. His interests lie in cryptography, modelling of computer viruses/worms in computer networks, cryptanalysis and ICT security with a focus in eVoting and eGovernment related security protocols and systems.

Anonymous Course Evaluations at Universities; The Patras University Pilot In this session we are going to demonstrate the Privacy-ABCs technology in a system that allows anonymous, remote course evaluations at Universities by certified students. We are going to describe the system architecture as well as the use cases and provide a complete demo of the system operation.

 

Ahmad Sabouri is a scientific researcher and doctoral candidate with the Deutsche Telekom Chair of Mobile Business and Multilateral Security at Goethe University Frankfurt. His main research interests include: Identity Management, Privacy and Cloud Computing. He has been involved in research actives and coordination of the ABC4Trust EU project since 2011.

ABC4Trust Architecture In this presentation we introduce the generic architecture model of Privacy-ABC Systems that was designed within the ABC4Trust project. More specifically, we focus on the involved entities and their interactions, and discuss how the layered architecture of ABC4Trust enables smooth integration of Privacy-ABCs to various applications.

 

Michael Østergaard received a Ph.D. in Computer Science in 2008 from the University of Aarhus, where he was part of the cryptography group. Currently he is working at Miracle A/S within the fields of IT security, penetration testing and software development. His research interests include cryptographic protocols with focus on privacy protection, as well as IT security in general.

ABC4Trust Reference ImplementationIn this presentation we introduce the different components of the ABC4Trust Reference Implementation and how they interact with each other, as well as various interfaces that are available to application developers. Finally we give a short demo, illustrating what it is possible to achieve in relatively short time, with the Reference Implementation.

 

Pascal Paillier is a public-key cryptography expert and has more than 16 years of industrial experience in IT security, with a specific interest for designing and developing side channel/fault-resistant cryptographic software for embedded architectures such as smart cards. His favorite research works include the design of public-key primitives, security proofs and more recently the design of hash functions (co-conceptor of the SHABAL hash function submitted to the NIST SHA-3 competition). Until 2009, Pascal was heading the Cryptography & Innovation expert group at Gemalto, the worldwide leader in smart card technologies. Co-founder of CryptoExperts, Pascal has published over 60 research papers and filed about 25 patents, most of which are commonly implemented in the smart card industry. Pascal is also an active member of ISO SC27 WG2, the expert group that defines ISO/IEC cryptography standards.

Smart Card Implementation – In this presentation, we will make a live demonstration of the ABC4Trust smart card: what it contains, what it does and how it works together with the ABCE to provide presentation proofs. A toy scenario will be used to show how the different objects are created and operated in the card.

 

Gert Læssøe Mikkelsen has a theoretical background in cryptography, and holds a PhD in computer science and cryptography from Aarhus University. He now works at the Alexandra Institute, in their security lab, where he in his daily work works with new technology in the field of digital identity management both in internal projects and in international research projects like the ABC4Trust Project.

Privacy-ABC technology on Mobile PhonesWhile the project's trials were using laptops and smart cards, it is also possible to use mobile devices like mobile phones or tablets. The advantage is, that most potential users already have one, so there is no need for additional hardware like smart cards and smart card readers. On the other side the usage of mobile devices raises some new challenges, as they are computationally less powerful than laptops, and less secure than special designed smart cards. These challenges will be discussed in this presentation, and we will show that despite these challenges it is possible to use mobile devices as a platform for Privacy-ABCs.

 

Jan Camenisch received a Diploma in Electrical Engineering in 1993 and a Ph.D. in Computer Science in 1998 both from ETH Zurich. From 1998 until 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 -- Zurich. Together with Anna Lysyanskaya, Jan invented the identity mixer protocols that are now part of the ABC4Trust platform. Jan recently got a Grant for "Personal Cryptography" from the European Research Council. His research interests include public key cryptography; cryptographic protocols, in particular those supporting privacy and anonymity; practical secure distributed computation; and privacy-enhancing technologies.

ABC4Trust as services in the cloudInstalling and initialising the different ABC4Trust components to obtain privacy-friendly authentication is non-trivial. The cloud promises to get rid of installation, software is just there to use. In this talk we explain how and to what extend the components of ABC4Trust can be run in the cloud. We finally show a demo that uses ABC4Trust services in the cloud. In fact, all participants can try the demo themselves and experience Privacy-ABCs live.

 

Demonstrators during Lunch Break

During the lunch break the speakers and further representatives of ABC4Trust’s partners will be available for questions and discussions.

Furthermore, Robert Seidl from ABC4Trust’s partner NSN will make accessible a demonstrator of the related project FI-Ware: A user visits a ‘File Store’ and selects one of 10 access policies which she can satisfy.  The user is then forwarded to the ‘Identity Agent’ and is requested to login. After successful authentication, the ‘Identity Agent’ fetches the user’s credential and generates a presentation token which will meet the chosen policy. The user forwards this token to the ‘File Store’ which then requests the ‘Verifier as a Service’ to check the token. If the cryptographic proof succeeds, the user is allowed to access the resource. Differences to the ABC4Trust pilot use-cases: The ‘user application’ is shifted into the cloud and handled by a trusted ‘Identity Agent’. Now the only prerequisite on the user side is a Google Chrome browser which enables mobile devices and ‘wearables’ to be used too. On top of this, the RESTful ABC4Trust interfaces of the Verifier and of the Issuer have been enhanced to include a simple form of authentication in order to prevent unauthorized access.

Robert Seidl studied Electrical Engineering at the Munich University of Applied Sciences. He received his diploma in 1993. Joining Rohde & Schwarz for a first period of practice he was involved in the introduction of digital cordless phones in Germany. Since 1995 he has been with Siemens AG in Munich. After 7 years of hard- and software development he entered the mobile network division in 2001. In 2007 he joined Nokia Siemens Networks (NSN) and has mainly been involved in the area of identity management, reliability, service access control and simplified access to services. He was responsible for NSN in European projects such as SIMPLICITY or SPICE and heading the group on Identity Management within NSN research. Today Mr. Seidl works in the research group of Nokia and is heading a team responsible for Data Analytics and Privacy. He is responsible for the EU funded projects ABC4Trust and FI-WARE.
