September, 7-12, 2014 IFIP Summer School 2014 hosted by ABC4Trust

The 9th international IFIP summer school on privacy and identity management for the future internet in the age of globalisation took place on September 7-12, 2014 in Patras, Greece.

This year's summer school was hosted by ABC4Trust consortium partner CTI - Computer Technology Institute and Press "Diophantus" located near the University of Patras.

This annual event is organised by the IFIP working groups 9.2, 9.5, 9.6/11.7, 11.4, 11.6 and special interest group 9.2.2. ABC4Trust co-organizes the joint effort of several research projects to keep the IFIP summer school series up. For the event in 2014 summer school was hosted by our Greek ABC4Trust partner CTI with Yannis Stamatiou as organizing committee chair. Further ABC4Trust involvement consisted of Marit Hansen (ULD) as general chair and Jan Camenisch (IBM) as a program committee co-chair.

The IFIP summer school 2014 was interactive in character, and composed of keynote lectures and workshops with master/PhD student presentations. The principle is to bring together junior and senior researchers and practitioners from multiple disciplines to discuss important questions concerning privacy and identity management and related issues in a global environment. To this end, contributions from students at the stage of preparing either a master’s or a PhD thesis are especially encouraged.

ABC4Trust was represented by two keynote speakers and an afternoon workshop, providing three parallel sessions. Furthermore, the project was addressed in several student papers.

Participants of the IFIP Summer School 2014 can view all slides of the ABC4Trust sessions here.

July 17, 2014 - ABC4Trust at the Greek Ministry of Foreign Affairs

After the successful operation of the Patras pilot, ABC4Trust was invited (through the University of Patras Innovation Office) to present its results at a one-day event organized by the Greek Ministry of Foreign Affairs (MFA).

The event will take place on July 17, 2014, at the amphitheatre “Kranidiotis” of the MFA at Akadimias 1 Str., Athens, Greece.

The goal of the event is to promote mature research results (which are ranked above 6 at the Technology Readiness Levels) to interested parties, who might include the immediate exploitation in their business plans.

Invitations were sent to ambassadors and finance/commerce State representatives of foreign countries, as well as to their Greek counterparts. Also, invitations were sent to representatives from the private and public sector in Greece.

 

ABC4Trust Workshop at the Cyber Security & Privacy Forum 2014 in Athens

ABC4Trust organised a workshop at this year’s  CSP Forum Conference, held in Athens, Greece. The workshop ‘ABC4Trust – Putting Privacy-ABCs into Practice’ consisted of two parts. (‘Track 12’ and ‘Track 15’ on the conference programme.)

All presentations can be found here.

Speakers:

Gregory Neven (IBM) - The Concept of Privacy-ABCs

Jonas Lindstrøm Jensen (Alexandra Institute) - Privacy-ABCs on Mobile Devices

Souheil Bcheri (Eurodocs AB) - Community Interaction Among Pupils

Yannis Stamatiou (Diophantus) - Privacy Preserving Course Evaluation in Educational Institutes

Ahmad Sabouri (Goethe University Frankfurt/Main) - Enabling Privacy Friendly Integration of Cloud Services into Enterprises

Chair: Hannah Obersteller (ULD)

In the first part, Gregory Neven introduced the audience to the idea and the functionalities of Privacy-enhancing Attribute-based Credentials (Privacy-ABCs). After describing existing identification schemes and their weaknesses, Dr. Neven explained the advantages of Privacy-ABCs. Privacy-ABCs allow the user to choose which information – in other words: which attribute – he is willing to reveal. In the following, he focused on the more advanced features such as pseudonyms, revocation, and inspection. While by default Privacy-ABCs allow the user to access a service completely anonymously, the optional feature “inspection” can be enabled if needed. This means, the identity of the user can be revealed conditionally. The user must be informed in advance if inspection is enabled and under which circumstances (inspection grounds) his identity may be revealed. The revocation feature allows the issuer of the credentials to revoke them. This might become necessary if a certain attribute of the user changes; e.g. if he is not a student anymore.

Jonas Lindstrøm Jensen showed examples of how Privacy-ABCs can be used on mobile devices. While the project’s trials were using laptops as devices, 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 hard ware like smart cards and smart card readers. Mr. Lindstrøm Jensen referred to new use cases and the security and privacy problems that, in turn, appear.

Souheil Bcheri presented the results of one of ABC4Trust’s trials. ABC4Trust set up a School Communication System at a Secondary School in Söderhamn/Sweden. Functionalities like chat and document sharing are provided as well as counselling sessions and political discussions. The pupils, their parents and teachers are enabled to access the network pseudonymously or anonymously, depending on the service they want to use. Since there had not been a similar application before, ABC4Trust had to create it from sketch. The network offers certain “rooms” – Restricted Areas – to certain group of users. Depending on the individual access policy of each of those Restricted Areas, there can be e.g. a chat room that allows access for everyone who can prove that she is not elder than 14 and a girl. The users can create own Restricted Areas and determine their access policies as well.

Building on what had been presented in the first part, in the second part Yannis Stamatiou reported on the results of the second trial of ABC4Trust, also by showing screenshots and video sequences. The project implemented a Course Evaluation System at the University of Patras, Greece. The students are enabled to evaluate their Courses anonymously. At the same time the system guarantees that only duly accredited students can participate in the evaluation. As an incentive to the students to participate in the trial, the students could choose to get another credential. This so-called Tombola credential allowed them to participate in a Tombola at the end of the semester. The inspection feature was used to reveal the identity of the winner. All other credentials were not inspected. The revocation feature was employed to allow the university to revoke a student’s credential when he leaves the university. After the explanation of the system, Prof. Stamatiou talked about the results of an anonymous questionnaire that was answered by the students who participated in the trial. According to the evaluation the students understood the functionality and also trusted the system. Prof. Stamatiou also reported on the future exploitation of the system.

Finally, Ahmad Sabouri gave a presentation on a special future use case of Privacy-ABCs: Use on the Cloud. After giving an introduction to Cloud Services in general, he talked about what might keep enterprises from using them. One major issue is privacy and identity concerns. Identity management in the cloud is different. Mr. Sabouri described the Privacy requirements in the Cloud. While the IdMaaS must not learn about the services the user accesses, the Cloud Provider may be neither able to link a user to his identity, nor to profile the user based on his different accesses. Furthermore, the Cloud Service Provider should not learn about the use of resources and services, while the enterprises should be able to audit those. Then, he explained in how far Privacy-ABCs meet those requirements and mapped the roles of the entities of a Privacy-ABC system.

Questions were answered during and after each presentation.

ABC4Trust Workshop at the Trust in Digital Life Trust Event 2014 in Vienna

The annual Trust in Digital Life event took place on April 7th and 8th, 2014 in Vienna.

The ABC4Trust Project organized Track 3 “Identity management” and offered a panel featuring a variety of current applications of Privacy-ABC. The workshop targeted everyone that wants to implement privacy-preserving identity management. The panel demonstrated that usable and trustworthy identity management systems are technically possible and in several cases already a working reality. In the track the following presentations were covered:

General technology presentation of ABCs in ABC4Trust

(Dr. Gregory Neven, IBM)

Privacy respecting ICT innovations in education: electronic course evaluations in higher education and beyond

(Prof. Yannis Stamatiou, Computer Technology Institute and Press)

Restrictive download of documents from cloud storage in FI-Ware

(Robert Seidl, Nokia Solutions and Networks)

Performance of privacy-enhancing cryptography on smartphones

(Dr. Jan Hajny, Brno University of Technology)

Information security supporting data protection

(Dr. Rodica Tirtea, ENISA)

 

Major questions and discussions in the panel:

  • What would be some interesting examples of Privacy-ABCs applications?
    Apart from the pilots of ABC4Trust that deal with privacy-friendly online course evaluation and privacy-friendly school community platform, one could consider e-government polls, age verification and public transportation ticketing to be very relevant problems that can be addressed using Privacy-ABCs.
  • There are so many cryptographic solutions to deal with privacy problems. Why to use ABC4Trust framework and not any other one?
    ABC4Trust framework is defined in a generic way based on the identified features that are required from Privacy-ABCs. Therefore it gives the opportunity to any crypto provider to implement the specified interfaces and therefore be pluggable to the framework. ABC4Trust is not limited to any specific technology and it also helps to avoid a lock-in situation.  
  • One of the major blocking factors in front of adoption of Privacy-ABCs concerns the application developers not being familiar with the crypto. What can be done in this regard?
    The ABC4Trust project has provided a crypto-agnostic API set to Privacy-ACBs, which relieves the burden of complicated crypto. The reference implementation of ABC4Trust is publicly available on Github along with documentations and integration examples for the developers.
  • How is it possible to convey the properties of Privacy-ABCs to the end users?
    Indeed a certain level of trust is needed for the ecosystem to work. Trust in the crypto, trust in the correct implementation of the crypto and trust in the correct deployment of the system are the minimum requirements. Perhaps there should be some consumer protection or verification agencies to help with gaining the trust of the end users in the system and the promised features.

 

February 28, 2014 ABC4Trust at EU Cybersecurity Strategy - High Level Conference in Brussels

Brussels, February, 28th, 2014: The ABC4Trust project is present at the "EU Cybersecurity Strategy - High Level Conference" with a booth and strong presence of the ABC4Trust members. The one-day Conference is organised by the European Commission, in cooperation with the European External Action Service.
Keynotes have been provided by Ms Neelie Kroes, Commission Vice-President for the Digital Agenda and Mr Maciej Popowski, Deputy Secretary General of the European External Action Service.
In her keynote Ms Neelie Kroes stated that in the field of cybersecurity we in Europe need to say “yes” to data protection and “no” to data protectionism. We also should not get too entangled in viewing ongoing revelations by Edward Snowden but recognize that cybersecurity is also about the aspects directly relevant for the citizens: People trusting that their personal data on social network sites are well protected; users understanding what their cloud service providers are offering, eID solutions allowing to securely authenticate towards services; or children’s sufficiently protected but also empowered to avoid online risks.
ABC4Trust addresses many of the aspects mentioned in the vice president’s keynote. The Swedish Pilot provides a school network for information exchange at a school where pupils are empowered to communicate securely within verified areas while retaining their anonymity to the extent possible or acting under pseudonyms. Data protection and data minimisation is a core feature built into Privacy-enhanced Attribute-based Credentials (Privacy-ABCs) – presumed that the systems are set up accordingly. The data minimisation principle states that (only) the data necessary for a given and defined purpose may be processed. Privacy-ABCs permit to remove data from a certificate that are unnecessary while retaining the integrity of the issuer’s signature for the remaining information.

At the High Level Conference on the EU Cybersecurity Strategy ABC4Trust is present with a booth where both ABC4Trust pilots are on display. Prof. Kai Rannenberg from ABC4Trust Presentation booth at High Level Conference with Souheil Bcheri, Yannis Stamatiou, Harald ZwingelbergGoethe University Frankfurt, Germany, is project lead of the ABC4Trust project. The Swedish school pilot is presented by Souheil Bcheri of Eurodocs. Prof. Yannis Stamatiou from The Computer Technology Institute & Press – Diophantus, Greece, shows the university pilot allowing anonymous evaluation of lectures. Harald Zwingelberg from the Unabhängigen Landeszentrum für Datenschutz, Germany, presents comments on legal aspects of Privacy-ABCs to support eID solutions across Europe.

Keynote Speaker Dr. Thomas Kremer, Member of Deutsche Telekom’s Board of Management for Data Privacy, Legal Affairs and Compliance, showing great interest in the ABC4Trust pilot systems

The ABC4Trust session

In June 2012 the EU Commission adopted a proposal for a “Regulation of the European Parliament and the Council on electronic identification and trust services for electronic transactions in the internal market” (COM/2012/238/FINAL, hereinafter eIDAS Regulation). The eIDAS Regulation aims to bring trust to electronic transactions in the European market by inter alia providing for a mutual recognition and acceptance of national eID solutions. To have its national eID solution recognized and accepted in other Member States the Member State of origin may notify its national eID solution to the commission. Provided a series of requirements are fulfilled such notified schemas must be recognized EU wide. At present, the draft eIDAS Regulation is open for discussion and comments in the European parliament. A session with expert input and discussions with the high level audience may positively influence the decisions on details of the Regulation. The eIDAS Regulation causes concerns that it may hinder or even block the further development of privacy-enhancing solutions in the field of electronic Identifiers (eIDs). Some of these aspects have been pointed out in the ABC4Trust position paper on the eIDAS Regulation.

The ABC4trust session on Thursday will focus on the potential of privacy-enhancing attribute-based credentials (Privacy-ABCs) in the field of eIDs. For this part, we will start with a quick introduction to the privacy-enhancing features of the solution, and to the ABC4Trust project as a whole followed by a more detailed description of the ABC4Trust architecture. Two different approaches for integrating Privacy-ABCs with eID systems will be discussed, and elaborated on the benefits of Privacy-ABCs when building privacy-respecting eID systems. ABC4Trust’s Greek university pilot where smartcards are deployed for a secure and anonymous authentication towards a system for evaluating lectures – deployable e.g. for online participation of citizens in local decisions, polls, or surveys is presented next. Finally a data protection-oriented view on the draft eIDAS Regulation will be provided, elaborating on how Privacy-ABCs could enhance future eIDs, showing which adaptations might be necessary to the current draft eIDAS Regulation in order to allow and support such adaptations. The last talk is intended to encourage an open discussion with the participants on these particular topics of the eIDAS Regulation.

The ABC4Trust project and privacy-enhancing Attribute-based Credentials – enabling data protection features for future electronic authentication, by Prof. Kai Rannenenberg,

The first talk will introduce the ABC4Trust project before central principles and functionalities of Privacy-ABCs will be described. The audience will learn how anonymous authentication can be performed trustworthy and securely bound to one person, e.g. the holder of an eID token, by deploying cryptographic mechanisms. Further, necessary features such as an issuance, presentation, and revocation of credentials will be discussed. Provided the user submitted her identity information in an encrypted container at time of authentication, the optional inspection feature allows to later identify an otherwise anonymous user under previously fixed conditions, e.g. if that user violated applicable laws.

The ABC4Trust Architecture – making Privacy-ABCs deployable and interoperable, by Dr. Ioannis Krontiris

The goal of the presentation is to show that Privacy-ABCs have become an attractive solution to offer privacy in eID systems. In particular, we will report on the progress being made within the ABC4Trust project in terms of bringing together different Privacy-ABC technologies and building a unified architecture for their interoperation.

ABC4Trust_architecute_diagram_with_involved_entities

Figure: A high level view of the ABC4Trust Architecture

Then, we will discuss some of the privacy and security threats that exist in today’s eID systems, and elaborate on the advantages of using Privacy-ABCs to address these threats. Following that, we will discuss two approaches for integrating Privacy-ABCs with eID systems, taking the German eID system as a case study. In the first approach, we show that by introducing a new entity in the current German eID system, the citizen can get a lot of the Privacy-ABCs advantages without further modifications. Then, we will concentrate on the possibility of putting Privacy-ABCs directly on smart cards, and we will present new results on performance, which demonstrate that it is now feasible for smart cards to support the required computations these mechanisms require.

 

Anonymous authentication for polls and surveys with Privacy ABCs – The ABC4Trust university pilot leading the path to more eID features for citizen eParticipation?, by Prof. Yannis Stamatiou

The presentation on the ABC4Trust university pilot is intends to show the results of one of the two pilots in ABC4Trust. The ABC4Trust project addresses the federation and “interchangeability” of technologies that support Privacy-ABCs. For this pilot, the participating students collect a series of credentials to verify that they are eligible to anonymously participate in an evaluation of the quality of a lecture. The pilot, whose operation may be presented during a demo at the CSP EU Forum, comprises the provision of credentials to the students of a Greek university that certifies, using Privacy-ABCs, a number of facts of the students (e.g. registered courses, class attendance information, etc.). Eligible Students will be able to anonymously provide feedback on courses and teachers they had during a semester by using proper credentials stored on their smart cards. The attribute selection feature here allows students to verify information such as their participation in a course, without giving away their name or matriculation number stored on the same eID token. The pilot thus also provides a good test bed for other types of polls, petitions, and other means of opinion making. Such features may be interesting to support for national eIDs enabling citizens to easily participate in local politics, petitions, or other means of direct democracy in governmental and private organisations.

 

The draft eIDAS Regulation and its impact on privacy preserving technologies in the field, namely Privacy-enhancing Attribute-based Credentials, by Harald Zwingelberg

The legal and policy oriented presentation on the draft eIDAS Regulation will summarize the currently foreseen framework described in chapter two of the draft eIDAS Regulation. European eID experts share the opinion that upcoming eID schemas should support data minimisation by allowing attribute selection and that pseudonymous or anonymous authentication should be possible and enforced on relying parties where necessary (see SSEDIC eID Adoption Survey p. 32 et seq.). However, the current draft of the eIDAS Regulation does not foresee data minimisation, nor does it require foreign services to adhere to the principle of data minimisation even if the national eID of the customer supports such features. Here, further development in the area of eIDs should not be hindered but rather encouraged, in order to raise hope that future versions of eIDs may support privacy enhancing solutions such as Privacy-ABCs or the already existing solution of the German national eID “neuer Personalausweis”.

Further, the national authentication service, which is mandatory for all notified eID schemas, is likely to be able to profile the behavior of the users by learning which services from outside of the own member state have been visited by the users. For the authentication services, but also for any other involved entities, clear data protection rules including maximum retention periods for personal data are necessary, and need to be incorporated in the eIDAS Regulation. This presentation will provide some potential solutions as basis for further discussion with the audience.
