Foreword from the Program Chairs These proceedings contain the papers selected for presentation at the 10th - ropean Symposium on Research in Computer Security (ESORICS), held S- tember 12–14, 2005 in Milan, Italy. In response to the call for papers 159 papers were submitted to the conf- ence. These paperswere evaluated on the basis of their signi?cance, novelty,and technical quality. Each paper was reviewed by at least three members of the program committee. The program committee meeting was held electronically, holding intensive discussion over a period of two weeks. Of the papers subm- ted, 27 were selected for presentation at the conference, giving an acceptance rate of about 16%. The conference program also includes an invited talk by Barbara Simons. There is a long list of people who volunteered their time and energy to put together the symposiom and who deserve acknowledgment. Thanks to all the members of the program committee, and the external reviewers, for all their hard work in evaluating and discussing papers. We are also very grateful to all those people whose work ensured a smooth organizational process: Pierangela Samarati, who served as General Chair, Claudio Ardagna, who served as P- licity Chair, Dieter Gollmann who served as Publication Chair and collated this volume, and Emilia Rosti and Olga Scotti for helping with local arrangements. Last, but certainly not least, our thanks go to all the authors who submitted papers and all the attendees. We hope you ?nd the program stimulating.

This book constitutes the refereed proceedings of the 12th European Symposium on Research in Computer Security, ESORICS 2007, held in Dresden, Germany in September 2007. It features 39 revised full papers. ESORICS is confirmed as the European research event in computer security. It presents original research contributions, case studies and implementation experiences that address any aspect of computer security, in theory, mechanisms, applications, or practical experience.

This book constitutes the refereed proceedings of the 4th European Symposium on Research in Computer Security, ESORICS '96, held in Rome, Italy, in September 1996 in conjunction with the 1996 Italian National Computer Conference, AICA '96. The 21 revised full papers presented in the book were carefully selected from 58 submissions. They are organized in sections on electronic commerce, advanced access control models for database systems, distributed systems, security issues for mobile computing, network security, theoretical foundations of security, and secure database architectures.

This book constitutes the proceedings of the 14th European Symposium on Research in Computer Security, ESORICS 2009, held in Saint-Malo, France, in September 2009. The 42 papers included in the book were carefully reviewed and selected from 220 papers. The topics covered are network security, information flow, language based security, access control, privacy, distributed systems security, security primitives, web security, cryptography, protocols, and systems security and forensics.

The EuropeanSymposium on Researchin Computer Security (ESORICS) has a tradition that goes back two decades. It tries to bring together the international research community in a top-quality event that covers all the areas of computer security, ranging from theory to applications. ESORICS 2010 was the 15th edition of the event. It was held in Athens, Greece, September 20-22, 2010. The conference received 201 submissions. The papers went through a careful review process. In a ?rst round, each paper - ceived three independent reviews. For the majority of the papers an electronic discussion was also organized to arrive at the ?nal decision. As a result of the review process, 42 papers were selected for the ?nal program, resulting in an - ceptance rate of as low as 21%. The authors of accepted papers were requested to revise their papers, based on the comments received. The program was c- pleted with an invited talk by Udo Helmbrecht, Executive Director of ENISA (European Network and Information Security Agency). ESORICS 2010 was organized under the aegisof three Ministries of the G- ernment of Greece, namely: (a) the Ministry of Infrastructure, Transport, and Networks, (b) the General Secretariat for Information Systems of the Ministry of Economy and Finance, and (c) the General Secretariat for e-Governance of the Ministry of Interior, Decentralization, and e-Government.

The two-volume set, LNCS 9878 and 9879 constitutes the refereed proceedings of the 21st European Symposium on Research in Computer Security, ESORICS 2016, held in Heraklion, Greece, in September 2016. The 60 revised full papers presented were carefully reviewed and selected from 285 submissions. The papers cover a wide range of topics in security and privacy, including data protection: systems security, network security, access control, authentication, and security in such emerging areas as cloud computing, cyber-physical systems, and the Internet of Things.
