Attribute Based Encryption And Access Control

This book covers a broader scope of Attribute-Based Encryption (ABE), from the background knowledge, to specific constructions, theoretic proofs, and applications. The goal is to provide in-depth knowledge usable for college students and researchers who want to have a comprehensive understanding of ABE schemes and novel ABE-enabled research and applications. The specific focus is to present the development of using new ABE features such as group-based access, ID-based revocation, and attributes management functions such as delegation, federation, and interoperability. These new capabilities can build a new ABE-based Attribute-Based Access Control (ABAC) solution that can incorporate data access policies and control into ciphertext. This book is also ideal for IT companies to provide them with the most recent technologies and research on how to implement data access control models for mobile and data-centric applications, where data access control does not need to rely on a fixed access control infrastructure. It’s also of interested to those working in security, to enable them to have the most recent developments in data access control such as ICN and Blockchain technologies. Features Covers cryptographic background knowledge for ABE and ABAC Features various ABE constructions to achieve integrated access control capabilities Offers a comprehensive coverage of ABE-based ABAC Provides ABE applications with real-world examples Advances the ABE research to support new mobile and data-centric applications

ACNS2008,the6thInternationalConferenceonAppliedCryptographyandN- work Security, was held in New York, New York, June 3–6, 2008, at Columbia University. ACNS 2008 was organized in cooperation with the International - sociation for Cryptologic Research (IACR) and the Department of Computer Science at Columbia University. The General Chairs of the conference were - gelos Keromytis and Moti Yung. The conference received 131 submissions, of which the Program Committee, chairedbyStevenBellovinandRosarioGennaro, selected 30 for presentation at the conference. The Best Student Paper Award was given to Liang Xie and Hui Song for their paper “On the E?ectiveness of Internal Patch Dissemination Against File-Sharing Worms” (co-authored with Sencun Zhu). These proceedings consist of revised versions of the presented papers. The revisions werenot reviewed.The authors bear full responsibility for the contents of their papers. Thereweremany submissionsof goodquality, and consequentlythe selection process was challenging and very competitive. Indeed, a number of good papers were not accepted due to lack of space in the program. The main considerations in selecting the program were conceptual and technical innovation and quality of presentation. As re?ected in the Call for Papers, an attempt was made to solicit and publish papers suggesting novel paradigms, original directions, or non-traditional perspectives.

This book constitutes the refereed proceedings of the 18th European Symposium on Computer Security, ESORICS 2013, held in Egham, UK, in September 2013. The 43 papers included in the book were carefully reviewed and selected from 242 papers. The aim of ESORICS is to further the progress of research in computer security by establishing a European forum for bringing together researchers in this area, by promoting the exchange of ideas with system developers and by encouraging links with researchers in related areas. The papers cover all topics related to security, privacy and trust in computer systems and networks.

This book constitutes the refereed proceedings of the 17th International Conference on Practice and Theory in Public-Key Cryptography, PKC 2014, held in Buenos Aires, Argentina, in March 2014. The 38 papers presented were carefully reviewed and selected from 145 submissions. The papers are organized in topical sections on chosen ciphertext security, re-encryption, verifiable outsourcing, cryptanalysis, identity and attribute-based encryption, enhanced encryption, signature schemes, related-key security, functional authentication, quantum impossibility, privacy, protocols.

The 10th International Workshop on Information Security Applications (WISA 2009) was held in Busan, Korea during August 25–27, 2009. The workshop was hosted by the Korea Institute of Information Security and Cryptology (KIISC), supported by the Electronics and Telecommunications Research Institute (ETRI) and the Korea Internet and Security Agency (KISA), sponsored by the Ministry of Public Administration and Security (MoPAS) and the Korea Communications Commission (KCC), financially sponsored by the ST. Ltd. The aim of the workshop was to serve as a forum for presenting new research and experimental results in the area of information security applications from academic communities as well as from industry. The workshop program covered a wide range of security aspects, from cryptography to systems and network security and experimental work as well. It was our great pleasure and honor to serve as the Program Committee Co-chairs of WISA2009. This year, too, the proceedings of the workshop were published in the LNCS series of Springer. The WISA 2009 Program Committee received 79 papers form 16 countries. This year the submissions were exceptionally strong, and the committee accepted 27 papers for the full paper presentation track. All the papers were carefully evaluated through blind peer-review by at least three members of the Program Comm- tee. We would like to say that acceptance is a great achievement since the selection process was highly competitive, and many good papers were not accepted.

This comprehensive new resource provides an introduction to fundamental Attribute Based Access Control (ABAC) models. This book provides valuable information for developing ABAC to improve information sharing within organizations while taking into consideration the planning, design, implementation, and operation. It explains the history and model of ABAC, related standards, verification and assurance, applications, as well as deployment challenges. Readers find authoritative insight into specialized topics including formal ABAC history, ABAC’s relationship with other access control models, ABAC model validation and analysis, verification and testing, and deployment frameworks such as XACML. Next Generation Access Model (NGAC) is explained, along with attribute considerations in implementation. The book explores ABAC applications in SOA/workflow domains, ABAC architectures, and includes details on feature sets in commercial and open source products. This insightful resource presents a combination of technical and administrative information for models, standards, and products that will benefit researchers as well as implementers of ABAC systems in the field.

These are the proceedings of Eurocrypt 2010, the 29th in the series of Eu- pean conferences on the Theory and Application of Cryptographic Techniques. The conference was sponsored by the International Association for Cryptologic Research and held on the French Riviera, May 30–June 3, 2010. A total of 191 papers were received of which 188 were retained as valid submissions. These were each assigned to at least three Program Committee members and a total of 606 review reports were produced. The printed record of the reviews and extensive online discussions that followed would be almost as voluminous as these proceedings. In the end 35 submissions were accepted with twosubmissionpairsbeingmergedtogive33paperspresentedattheconference. The ?nal papers in these proceedings were not subject to a second review before publication and the authors are responsible for their contents. The ProgramCommittee, listed on the next page, deservesparticular thanks for all their hard work, their outstanding expertise, and their constant c- mitment to all aspects of the evaluation process. These thanks are of course extended to the very many external reviewers who took the time to help out during the evaluation process.It was also a greatpleasure to honor and welcome Moti Yung who gave the 2010 IACR Distinguished Lecture.
