This book constitutes the thoroughly refereed post-conference proceedings of the IFIP WG 11.4 International Workshop on Open Problems in Network Security, iNetSec 2011, held in Lucerne, Switzerland, in June 2011, co-located and under the auspices of IFIP SEC 2011, the 26th IFIP TC-11 International Information Security Conference. The 12 revised full papers were carefully reviewed and selected from 28 initial submissions; they are fully revised to incorporate reviewers' comments and discussions at the workshop. The volume is organized in topical sections on assisting users, malware detection, saving energy, policies, and problems in the cloud.

This book constitutes the refereed proceedings of the 17th International Conference on Cryptology and Network Security, CANS 2018, held in Naples, Italy, in September/October 2018. The 26 full papers were carefully reviewed and selected from 79 submissions. The papers are organized in the following topical sections: privacy; Internet misbehavior and protection; malware; symmetric key cryptography; signatures; cryptanalysis; cryptographic primitives; and cryptographic protocols.

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.

At the end of the PrimeLife EU project, a book will contain the main research results. It will address primarily researchers. In addition to fundamental research it will contain description of best practice solutions.

The working group WG 11.4 of IFIP ran an iNetSec conference a few times in the past, sometimes together with IFIP security conference, sometimes as a stand-alone workshop with a program selected from peer-reviewed submissions. When we were elected to chair WG 11.4 we asked ourselveswhether the security and also the computer science community at large bene?ts from this workshop. In particular, as there aremany (too many?) securityconferences, it has become di?cult to keep up with the ?eld. After having talked to many colleagues, far too many to list all of them here, we decided to try a di?erent kind of workshop: one where people would attend to discuss open research topics in our ?eld, as typically only happens during the co?ee breaks of ordinary conferences. Toenablethiswecalledforabstractsof2pageswheretheauthorsoutlinethe open problems that they would like to discuss at the workshop, the intent being that the author would be given 15 minutes to present the topic and another 15 minutes for discussion. These abstracts were then read by all members of the Program Committee and ranked by them according to whether they thought thiswouldleadtoaninterestingtalk and discussion. We then simply selected the abstracts that got the best rankings. We were happy to see this result in many really interesting talks and disc- sions in the courseof the workshop.Ofcourse, these lively anddirect discussions are almost impossible to achieve in a printed text. Still, we asked the authors to distill the essence of these discussions into full papers. The results are in your hand

This book constitutes the thoroughly refereed post-conference proceedings of the 7th European Workshop on Public Key Infrastructures, Services and Applications, EuroPKI 2010, held in Athens, Greece, in September 2010. The 14 revised full papers presented together with an invited article were carefully reviewed and selected from 41 submissions. The papers are organized in topical sections on authentication mechanisms; privacy preserving techniques; PKI & PKC applications; electronic signature schemes; identity management.

This book constitutes the refereed post-conference proceedings of the IFIP WG 11.4 International Workshop, iNetSec 2010, held in Sofia, Bulgaria, in March 2010. The 14 revised full papers presented together with an invited talk were carefully reviewed and selected during two rounds of refereeing. The papers are organized in topical sections on scheduling, adversaries, protecting resources, secure processes, and security for clouds.

This book constitutes the thoroughly refereed post-proceedings of the 8th International Workshop on Information Hiding, IH 2006, held in Alexandria, VA, USA in July 2006.

The 25 revised full papers presented were carefully selected from over 70 papers submitted. The papers are organized in topical sections on watermarking, information hiding and networking, data hiding in unusual content, fundamentals, software protection, steganalysis, steganography, and subliminal channels.

These are the proceedings of Eurocrypt 2004, the 23rd Annual Eurocrypt C- ference. The conference was organized by members of the IBM Zurich Research Laboratory in cooperation with IACR, the International Association for Cr- tologic Research. Theconferencereceivedarecordnumberof206submissions,outofwhichthe program committee selected 36 for presentation at the conference (three papers were withdrawn by the authors shortly after submission). These proceedings contain revised versions of the accepted papers. These revisions have not been checked for correctness, and the authors bear full responsibility for the contents of their papers. The conference program also featured two invited talks. The ?rst one was the 2004 IACR Distinguished Lecture given by Whit?eld Di?e. The second invited talk was by Ivan Damg? ard who presented "Paradigms for Multiparty Computation. " The traditional rump session with short informal talks on recent results was chaired by Arjen Lenstra. The reviewing process was a challenging task, and many good submissions had to be rejected. Each paper was reviewed independently by at least three members of the program committee, and papers co-authored by a member of the program committee were reviewed by at least six (other) members. The individual reviewing phase was followed by profound and sometimes lively d- cussions about the papers, which contributed a lot to the quality of the ?nal selection. Extensive comments were sent to the authors in most cases.
