Book Description
In the last few years we have all become daily users of Internet banking, social networks and cloud services. Preventing malfunctions in these services and protecting the integrity of private data from cyber attack are both current preoccupations of society at large. While modern technologies have dramatically improved the quality of software, the computer science community continues to address the problems of security by developing a theory of formal verification; a body of methodologies, algorithms and software tools for finding and eliminating bugs and security hazards. This book presents lectures delivered at the NATO Advanced Study Institute (ASI) School Marktoberdorf 2015 – ‘Verification and Synthesis of Correct and Secure Systems'. During this two-week summer school, held in Marktoberdorf, Germany, in August 2015, the lecturers provided a comprehensive view of the current state-of-the-art in a large variety of subjects, including: models and techniques for analyzing security protocols; parameterized verification; synthesis of reactive systems; software model checking; composition checking; programming by examples; verification of current software; two-player zero-sum games played on graphs; software security by information flow; equivalents – combinatorics; and analysis of synthesis with 'Big Code'. The Marktoberdorf ASIs have become a high-level scientific nucleus of the international scientific network on formal methods, and one of the major international computer science summer schools. This book will be of interest to all those seeking an overview of current theories and applications in formal verification and security.

Book Description
Security protocols employed in practice are used in our everyday life and we heavily depend on their security. The complexity of these protocols still poses a big challenge on their comprehensive analysis. To cope with this complexity, a promising approach is modular security analysis based on universal composability frameworks, such as Canetti's UC model. This appealing approach has, however, only very rarely been applied to the analysis of (existing) real-world protocols. Either the analysis was not fully modular or it could only be applied to idealized variants of the protocols. The main goal of this thesis therefore is to push modular protocol analysis as far as possible, but without giving up on accurate modeling. Our main contributions in a nutshell: An ideal functionality for symmetric key cryptography that provides a solid foundation for faithful, composable cryptographic analysis of real-world security protocols. A computational soundness result of formal analysis for key exchange protocols that use symmetric encryption. Novel universal and joint state composition theorems that are applicable to the analysis of real-world security protocols. Case studies on several security protocols: SSL/TLS, IEEE 802.11i (WPA2), SSH, IPsec, and EAP-PSK. We showed that our new composition theorems can be used for a faithful, modular analysis of these protocols. In addition, we proved composable security properties for two central protocols of the IEEE standard 802.11i, namely the 4-Way Handshake Protocol and the CCM Protocol. This constitutes the first rigorous cryptographic analysis of these protocols. While our applications focus on real-world security protocols, our theorems, models, and techniques should be useful beyond this domain.

Book Description
The topics of this thesis are the modal μ-calculus and parity games. The modal μ-calculus is a common logic for model-checking in computer science. The model-checking problem of the modal μ-calculus is polynomial time equivalent to solving parity games, a 2-player game on labeled directed graphs. We present the first FPT algorithms (fixed-parameter tractable) for the model-checking problem of the modal μ-calculus on restricted classes of graphs, specifically on classes of bounded Kelly-width or bounded DAG-width. In this process we also prove a general decomposition theorem for the modal μ-calculus and define a useful notion of type for this logic. Then, assuming a class of parity games has a polynomial time algorithm solving it, we consider the problem of extending this algorithm to larger classes of parity games. In particular, we show that joining games, pasting games, or adding single vertices preserves polynomial-time solvability. It follows that parity games can be solved in polynomial time if their underlying undirected graph is a tournament, a complete bipartite graph, or a block graph. In the last chapter we present the first non-trivial formal proof about parity games. We explain a formal proof of positional determinacy of parity games in the proof assistant Isabelle/HOL. Die Themen dieser Dissertation sind der modale μ-Kalkül und Paritätsspiele. Der modale μ-Kalkül ist eine häufig eingesetzte Logik im Bereich des Model-Checkings in der Informatik. Das Model-Checking-Problem des modalen μ-Kalküls ist polynomialzeitäquivalent zum Lösen von Paritätsspielen, einem 2-Spielerspiel auf beschrifteten, gerichteten Graphen. Wir präsentieren die ersten FPT-Algorithmen (fixed-parameter tractable) für das Model-Checking-Problem des modalen μ-Kalküls auf Klassen von Graphen mit beschränkter Kelly-Weite oder beschränkter DAG-Weite. Für diesen Zweck beweisen wir einen allgemeineren Zerlegungssatz für den modalen μ-Kalkül und stellen eine nützliche Definition von Typen für diese Logik vor. Angenommen, eine Klasse von Paritätsspielen hat einen Polynomialzeit-Lösungs-Algorithmus, betrachten wir danach das Problem, diese Klassen zu erweitern auf eine Weise, sodass Polynomialzeit-Lösbarkeit erhalten bleibt. Wir zeigen, dass dies beim Join von Paritätsspielen, beim Pasting und beim Hinzufügen einzelner Knoten der Fall ist. Wir folgern daraus, dass das Lösen von Paritätsspielen in Polynomialzeit möglich ist, falls der unterliegende ungerichtete Graph ein Tournament, ein vollständiger bipartiter Graph oder ein Blockgraph ist. Im letzten Kapitel präsentieren wir den ersten nicht-trivialen formalen Beweis über Paritätsspiele. Wir stellen einen formalen Beweis für die positionale Determiniertheit von Paritätsspielen im Beweis-Assistenten Isabelle/HOL vor.
