This festschrift was written in honor of Andrew William (Bill) Roscoe on the occasion of his 60th birthday, and features tributes by Sir Tony Hoare, Stephen Brookes, and Michael Wooldridge. Bill Roscoe is an international authority in process algebra, and has been the driving force behind the development of the FDR refinement checker for CSP. He is also world renowned for his pioneering work in analyzing security protocols, modeling information flow, human-interactive security, and much more. Many of these areas are reflected in the 15 invited research articles in this festschrift, and in the presentations at the "BILL-60" symposium held in Oxford, UK, on January 9 and 10, 2017.

The three-volume set LNCS 13042, LNCS 13043 and LNCS 13044 constitutes the refereed proceedings of the 19th International Conference on Theory of Cryptography, TCC 2021, held in Raleigh, NC, USA, in November 2021. The total of 66 full papers presented in this three-volume set was carefully reviewed and selected from 161 submissions. They cover topics on proof systems, attribute-based and functional encryption, obfuscation, key management and secure communication.

This book constitutes the refereed proceedings of the 4th International Information Security Practice and Experience Conference, ISPEC 2008, held in Sydney, Australia, in May 2008. The 29 revised full papers were carefully reviewed and selected from 95 submissions. The papers cover a wide range of topics in mathematics, computer science and security applications, including authentication and digital signatures, privacy, encryption and hash-function algorithms, security analysis, network security, access control, security devices, pairing and elliptic curve based security practice, security computation and so forth.

This book constitutes the refereed proceedings of the 5th International Conference on Applied Cryptography and Network Security, ACNS 2007, held in Zhuhai, China, June 2007. The 31 revised full papers cover signature schemes, computer and network security, cryptanalysis, group-oriented security, cryptographic protocols, anonymous authentication, identity-based cryptography, and security in wireless, ad-hoc, and peer-to-peer networks.

This book constitutes the refereed proceedings of the 6th International Conference on Provable Security, ProvSec 2012, held in Chengdu, China, in September 2012. The 16 full papers and 4 short papers presented were carefully reviewed and selected from 66 submissions. The papers are grouped in topical sections on signature schemes, foundations, leakage resilence and key escrow, encryption schemes, and information theoretical security.

This book presents a collection of research papers that address the challenge of how to develop software in a principled way that, in particular, enables reasoning. The individual papers approach this challenge from various perspectives including programming languages, program verification, and the systematic variation of software. Topics covered include programming abstractions for concurrent and distributed software, specification and verification techniques for imperative programs, and development techniques for software product lines. With this book the editors and authors wish to acknowledge – on the occasion of his 60th birthday – the work of Arnd Poetzsch-Heffter, who has made major contributions to software technology throughout his career. It features articles on Arnd’s broad research interests including, among others, the implementation of programming languages, formal semantics, specification and verification of object-oriented and concurrent programs, programming language design, distributed systems, software modeling, and software product lines. All contributing authors are leading experts in programming languages and software engineering who have collaborated with Arnd in the course of his career. Overall, the book offers a collection of high-quality articles, presenting original research results, major case studies, and inspiring visions. Some of the work included here was presented at a symposium in honor of Arnd Poetzsch-Heffter, held in Kaiserslautern, Germany, in November 2018.

This book discusses the issues and challenges in Online Social Networks (OSNs). It highlights various aspects of OSNs consisting of novel social network strategies and the development of services using different computing models. Moreover, the book investigates how OSNs are impacted by cutting-edge innovations.

The two volume set LNCS 12972 + 12973 constitutes the proceedings of the 26th European Symposium on Research in Computer Security, ESORICS 2021, which took place during October 4-8, 2021. The 71 full papers presented in this book were carefully reviewed and selected from 351 submissions. They were organized in topical sections as follows: Part I: network security; attacks; fuzzing; malware; user behavior and underground economy; blockchain; machine learning; automotive; anomaly detection; Part II: encryption; cryptography; privacy; differential privacy; zero knowledge; key exchange; multi-party computation.
