Attribute Based Credentials For Trust

The need for information privacy and security continues to grow and gets increasingly recognized. In this regard, Privacy-preserving Attribute-based Credentials (Privacy-ABCs) are elegant techniques to provide secure yet privacy-respecting access control. This book addresses the federation and interchangeability of Privacy-ABC technologies. It defines a common, unified architecture for Privacy-ABC systems that allows their respective features to be compared and combined Further, this book presents open reference implementations of selected Privacy-ABC systems and explains how to deploy them in actual production pilots, allowing provably accredited members of restricted communities to provide anonymous feedback on their community or its members. To date, credentials such as digitally signed pieces of personal information or other information used to authenticate or identify a user have not been designed to respect the users’ privacy. They inevitably reveal the identity of the holder even though the application at hand often needs much less information, e.g. only the confirmation that the holder is a teenager or is eligible for social benefits. In contrast, Privacy-ABCs allow their holders to reveal only their minimal information required by the applications, without giving away their full identity information. Privacy-ABCs thus facilitate the implementation of a trustworthy and at the same time privacy-respecting digital society. The ABC4Trust project as a multidisciplinary and European project, gives a technological response to questions linked to data protection.

This book contains a range of keynote papers and submitted papers presented at the 9th IFIP WG 9.2, 9.5, 9.6/11.7, 11.4, 11.6/SIG 9.2.2 International Summer School, held in Patras, Greece, in September 2014. The 9 revised full papers and 3 workshop papers included in this volume were carefully selected from a total of 29 submissions and were subject to a two-step review process. In addition, the volume contains 5 invited keynote papers. The regular papers are organized in topical sections on legal privacy aspects and technical concepts, privacy by design and privacy patterns and privacy technologies and protocols.

This book constitutes the refereed proceedings of the 11th International Conference on Trust and Privacy in Digital Business, TrustBus 2014, held in Munich, Germany, in September 2014 in conjunction with DEXA 2014. The 16 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in the following topical sections: trust management; trust metrics and evaluation models; privacy and trust in cloud computing; security management; and security, trust, and privacy in mobile and pervasive environments.

As is common practice in research, many new cryptographic techniques have been developed to tackle either a theoretical question or foreseeing a soon to become reality application. Cloud computing is one of these new areas, where cryptography is expected to unveil its power by bringing striking new features to the cloud. Cloud computing is an evolving paradigm, whose basic attempt is to shift computing and storage capabilities to external service providers. This resource offers an overview of the possibilities of cryptography for protecting data and identity information, much beyond well-known cryptographic primitives such as encryption or digital signatures. This book represents a compilation of various recent cryptographic primitives, providing readers with the features and limitations of each.

This book contains selected papers presented at the 12th IFIP WG 9.2, 9.5, 9.6/11.7, 11.6/SIG 9.2.2 International Summer School on Privacy and Identity Management, held in Ispra, Italy, in September 2017. The 12 revised full papers, 5 invited papers and 4 workshop papers included in this volume were carefully selected from a total of 48 submissions and were subject to a three-phase review process. The papers combine interdisciplinary approaches to bring together a host of perspectives: technical, legal, regulatory, socio-economic, social, societal, political, ethical, anthropological, philosophical, and psychological. They are organized in the following topical sections: privacy engineering; privacy in the era of the smart revolution; improving privacy and security in the era of smart environments; safeguarding personal data and mitigating risks; assistive robots; and mobility and privacy.

This book constitutes revised selected papers from the First Annual Privacy Forum, APF 2012, held in Limassol, Cyprus, in October 2012. The 13 revised papers presented in this volume were carefully reviewed and selected from 26 submissions. They are organized in topical sections named: modelling; privacy by design; identity management and case studies.

This book contains revised selected papers from the 22nd International Conference on Selected Areas in Cryptography, SAC 2015, held in Sackville, NB, Canada in August 2015. The 26 full papers and 3 short papers presented in this volume were carefully reviewed and selected from 91 submissions. They are organized in topical sections named: privacy enhancing technologies; cryptanalysis of symmetric-key primitives; implementation of cryptographic schemes; short papers; privacy preserving data processing; side channel attacks and defenses; new cryptographic constructions; authenticated encryption; on the hardness of mathematical problems; and cryptanalysis of authenticated encryption schemes.

The six volumes LNCS 11619-11624 constitute the refereed proceedings of the 19th International Conference on Computational Science and Its Applications, ICCSA 2019, held in Saint Petersburg, Russia, in July 2019. The 64 full papers, 10 short papers and 259 workshop papers presented were carefully reviewed and selected form numerous submissions. The 64 full papers are organized in the following five general tracks: computational methods, algorithms and scientific applications; high performance computing and networks; geometric modeling, graphics and visualization; advanced and emerging applications; and information systems and technologies. The 259 workshop papers were presented at 33 workshops in various areas of computational sciences, ranging from computational science technologies to specific areas of computational sciences, such as software engineering, security, artificial intelligence and blockchain technologies.
