This book deals with the problem of finding suitable languages that can represent specific classes of Petri nets, the most studied and widely accepted model for distributed systems. Hence, the contribution of this book amounts to the alphabetization of some classes of distributed systems. The book also suggests the need for a generalization of Turing computability theory. It is important for graduate students and researchers engaged with the concurrent semantics of distributed communicating systems. The author assumes some prior knowledge of formal languages and theoretical computer science.

Formal Methods for Open Object-Based Distributed Systems presents the leading edge in several related fields, specifically object-orientated programming, open distributed systems and formal methods for object-oriented systems. With increased support within industry regarding these areas, this book captures the most up-to-date information on the subject. Many topics are discussed, including the following important areas: object-oriented design and programming; formal specification of distributed systems; open distributed platforms; types, interfaces and behaviour; formalisation of object-oriented methods. This volume comprises the proceedings of the International Workshop on Formal Methods for Open Object-based Distributed Systems (FMOODS), sponsored by the International Federation for Information Processing (IFIP) which was held in Florence, Italy, in February 1999. Formal Methods for Open Object-Based Distributed Systems is suitable as a secondary text for graduate-level courses in computer science and telecommunications, and as a reference for researchers and practitioners in industry, commerce and government.

FOSAD has been one of the foremost educational events established with the goal of disseminating knowledge in the critical area of security in computer systems and networks. Offering a timely spectrum of current research in foundations of security, FOSAD also proposes panels dedicated to topical open problems, and giving presentations about ongoing work in the field, in order to stimulate discussions and novel scientific collaborations. This book presents thoroughly revised versions of nine tutorial lectures given by leading researchers during three International Schools on Foundations of Security Analysis and Design, FOSAD, held in Bertinoro, Italy, in September 2010 and August/September 2011. The topics covered in this book include privacy and data protection; security APIs; cryptographic verification by typing; model-driven security; noninterfer-quantitative information flow analysis; and risk analysis.

This volume contains the proceedings of the 7th Conference on Computational Methods in Systems Biology (CMSB 2009), held in Bologna, from August 31 to September 1, 2009. The ?rst CMSB was held in Trento in 2003, bringing together life scientists, computer scientists, engineers and physicists. The goal was to promote the c- vergence of di?erent disciplines aiming at a new understanding and description of biological systems, ?rmly ground in formal models, supported by compu- tionallanguagesandtools, ando?eringnew methodsofanalysis.The conference then moved to Paris in 2004, Edinburgh in 2005, Trento in 2006, Edinburgh in 2007 and Rostock/Warnemunde ] in 2008. This year the conference attracted about 45 submissions form 18 countries, mainly from Europe and North America, but also from Asia and Australia. We wish to thank all authors for their interest in CMSB 2009. After careful disc- sions, the Programme Committee eventually selected 18 papers for presentation at the conference. Each of them was accurately refereed by at least three - viewers, who delivered detailed and insightful comments and suggestions. The Conference Chairmen warmly thank all the members of the Programme C- mittee and all their sub-referees for the excellent support they gave, as well as for the friendly and constructive discussions. We also would like to thank the authorsfor havingrevisedtheir papers to addressthe comments andsuggestions by the referees."

Concrete details of low-level attacks anddefensesaregiveninthe caseof CandC++softwarecompiledinto machine code. Fabio Martinelli and Paolo Mori describe a solution to improve the Java native security support. Two examples of the application of the proposed so- tion, with history-based monitoring of the application behavior, are given in the case of grid computing and mobile devices. The purpose of the chapter by Javier Lopez, Cristina Alcaraz, and Rodrigo Roman is to review and discuss critical information infrastructures, and show how to protect their functionalities and performance against attacks. As an example, the chapter also discusses the role of wireless sensor networks technology in the protection of these infrastructures. The paper by Liqun Chen is a survey in the area of asymmetric key cryp- graphic methodologies for identity-based cryptography.

This book constitutes the refereed proceedings of the 8th IFIP WG 6.1 International Conference on Formal Methods for Open Object-Based Distributed Systems, FMOODS 2006, held in Bologna, Italy, June 2006. The book presents 16 revised full papers together with an invited paper and abstracts of 2 invited talks. Coverage includes component- and model-based design, service-oriented computing, software quality, modeling languages implementation, formal specification, verification, validation, testing, and service-oriented systems.

The increasing relevance of security to real-life applications, such as electronic commerce and Internet banking, is attested by the fast-growing number of - search groups, events, conferences, and summer schools that address the study of foundations for the analysis and the design of security aspects. The Int- national School on Foundations of Security Analysis and Design (FOSAD, see http: //www.sti.uniurb.it/events/fosad/)has been one of the foremost events - tablishedwiththegoalofdisseminatingknowledgeinthiscriticalarea, especially for young researchers approaching the ?eld and graduate students coming from less-favoured and non-leading countries. The FOSAD school is held annually at the Residential Centre of Bertinoro (http: //www.ceub.it/), in the fascinating setting of a former convent and ep- copal fortress that has been transformed into a modern conference facility with computing services and Internet access. Since the ?rst school, in 2000, FOSAD hasattractedmorethan250participantsand50lecturersfromallovertheworld. A collection of tutorial lectures from FOSAD 2000 was published in Springer s LNCS volume 2171. Some of the tutorials given at the two successive schools (FOSAD 2001 and 2002) are gathered in a second volume, LNCS 2946. To c- tinue this tradition, the present volume collects a set of tutorials fromthe fourth FOSAD, held in 2004, and from FOSAD 2005."

Security is a rapidly growing area of computer science, with direct and increasing relevance to real-life applications, such as Internet transactions, e-commerce, information protection, network and systems security, etc. Foundations for the analysis and design of security features of such applications are badly needed in order to validate and prove their correctness.

This book presents thoroughly revised versions of six tutorial lectures given by leading researchers during two International Schools on Foundations of Security Analysis and Design, FOSAD 2001/2002, held in Bertinoro, Italy, in September 2001 and September 2002. The lectures are devoted to:

- Formal Approaches to Approximating Noninterference Properties

- The Key Establishment Problem

- Name-Passing Calculi and Cryptoprimitives

- Classification of Security Properties; Network Security

- Cryptographic Algorithms for Multimedia Traffic

- Security for Mobility
