Principles of Program Analysis

Program analysis utilizes static techniques for computing reliable information about the dynamic behavior of programs. Applications include compilers (for code improvement), software validation (for detecting errors) and transformations between data representation (for solving problems such as Y2K). This book is unique in providing an overview of the four major approaches to program analysis: data flow analysis, constraint-based analysis, abstract interpretation, and type and effect systems. The presentation illustrates the extensive similarities between the approaches, helping readers to choose the best one to utilize.

This textbook is an introduction to the use of formal methods ranging from semantics of key programming constructs to techniques for the analysis and verification of programs. The authors use program graphs as the mechanism for representing the control structure of programs in order to find a balance between generality and conceptual complexity. The early chapters on program graphs and the Guarded Commands language are sufficient introduction for most readers to then enjoy a plug-and-play approach to the remaining chapters. These explain formal methods for analysing the behaviour of programs in various ways ranging from verification, via program analysis and language-based security, to model checking. The remaining chapters present language extensions with procedures and concurrency and cover their semantics. The book is suitable for advanced undergraduate and graduate courses in software development, and the text is supported throughout with exercises of varying grades of difficulty. The authors have developed an online learning environment that allows students to create examples beyond those covered in the main text, and in the book appendices they present programming projects aimed at implementing central parts of the development using the functional language F#.

Formal Methods

Semantics will play an important role in the future development of software systems and domain-specific languages. This book provides a needed introductory presentation of the fundamental ideas behind these approaches, stresses their relationship by formulating and proving the relevant theorems, and illustrates the applications of semantics in computer science. Historically important application areas are presented together with some exciting potential applications. The text investigates the relationship between various methods and describes some of the main ideas used, illustrating these by means of interesting applications. The book provides a rigorous introduction to the main approaches to formal semantics of programming languages.

Semantics with Applications: An Appetizer

Both functional and concurrent programming are relatively new paradigms with great promise. In this book, a survey is provided of extensions to Standard ML, one of the most widely used functional languages, with new primitives for concurrent programming. Computer scientists and graduate students will find this a valuable guide to this topic.

This open access book constitutes the proceedings of the 8th International Conference on Principles of Security and Trust, POST 2019, which took place in Prague, Czech Republic, in April 2019, held as part of the European Joint Conference on Theory and Practice of Software, ETAPS 2019. The 10 papers presented in this volume were carefully reviewed and selected from 27 submissions. They deal with theoretical and foundational aspects of security and trust, including on new theoretical results, practical applications of existing foundational ideas, and innovative approaches stimulated by pressing practical problems.

This volume contains the proceedings of the fourth edition of the International Symposium on Trustworthy Global Computing (TGC 2008) that was held in Barcelona, Spain, November 3-4, 2008. The Symposium on Trustworthy Global Computing is an international annual venue dedicated to safe and reliable c- putation in global computers. It focuses on providing frameworks, tools, and protocolsfor constructing well-behavedapplications and onreasoningrigorously about their behavior and properties. The related models of computation inc- porate code and data mobility over distributed networks with highly dynamic topologies and heterogeneous devices. This volume contains one invited paper from Gianluigi Zavattaro and co- thors, as well as the revised versions of the 12 contributed papers; these versions take into account both the referees' reports and the discussions that took place during the symposium. The Program Committee selected 12 papers from 26 submissions. Every submission was reviewed by at least three members of the Program Committee. In addition, the Program Committee sought the opinions of additional referees, selected because of their expertise in particular topics. We are grateful to Andrei Voronkov for his EasyChair system that helped us to manage these discussions. We would like to thank the authors who submitted paperstotheconference,the membersofthe ProgramCommittee,andthead- tional reviewersfor their excellent work. We would also like to thank the invited speakers to TGC 2008, Giuseppe Ateniese, Sophia Drossopoulou, and Gianluigi Zavattaro.

Trustworthy Global Computing

This book constitutes the thoroughly refereed post-conference proceedings of the 4th International Symposium on Trustworthy Global Computing, TGC 2008 held in Barcelona, Spain, in November 2008. The 12 revised papers presented together with one invited paper were carefully selected from 26 submissions during two rounds of reviewing and improvement. The TGC 2008 symposium papers focus on providing tools and frameworks for constructing well-behaved applications and for reasoning about their behavior and properties in models of computation that incorporate code and data mobility over distributed networks with highly dynamic topologies and heterogeneous devices.
