Reinhard Wilhelm's career in Computer Science spans more than a third of a century. During this time, he has made numerous research contributions to the areas of programming languages, compilers and compiler generators, static program analysis, program transformation, algorithm animation, and real-time systems; co-founded a company to transfer some of these ideas to industry; held the Chair for Programming Languages and Compiler Construction at Saarland University; and served since its inception in 1990 as the Scientific Director of the International Conference and Research Center for Computer Science at Schloss Dagstuhl.

This Festschrift volume, published to honor Reinhard Wilhelm on his 60th Birthday on June 10, 2006, includes 15 refereed papers by leading researchers, his graduate students and research collaborators, as well as current and former colleagues, who all attended a celebratory symposium held at Schloss Dagstuhl, Germany. The articles of this volume thus serve also as the proceedings of the aforementioned Dagstuhl symposium.

Increasingly our critical infrastructures are reliant on computers. We see examples of such infrastructures in several domains, including medical, power, telecommunications, and finance. Although automation has advantages, increased reliance on computers exposes our critical infrastructures to a wider variety and higher likelihood of accidental failures and malicious attacks. Disruption of services caused by such undesired events can have catastrophic effects, such as disruption of essential services and huge financial losses. The increased reliance of critical services on our cyberinfrastructure and the dire consequences of security breaches have highlighted the importance of information security. Authorization, security protocols, and software security are three central areas in security in which there have been significant advances in developing systematic foundations and analysis methods that work for practical systems. This book provides an introduction to this work, covering representative approaches, illustrated by examples, and providing pointers to additional work in the area.
