Book excerpt: LA VERIFICATION DE MODELE (MODEL CHECKING) EST UNE TECHNIQUE PERMETTANT DE VERIFIER LE COMPORTEMENT D'UNE MACHINE D'ETATS FINIS SPECIFIE AU MOYEN D'UNE PROPRIETE EXPRIMEE DANS UNE LOGIQUE TEMPORELLE. EN COMBINANT CETTE METHODE AVEC UNE REPRESENTATION SYMBOLIQUE PAR ARBRES DE DECISION BINAIRES, IL EST POSSIBLE DE TRAITER DES EXEMPLES DE TAILLE IMPORTANTE. UN PREMIER OBSTACLE A L'UTILISATION PRATIQUE DE CES METHODES RESTE LA COMPLEXITE DES ALGORITHMES UTILISES. NOUS PROPOSONS UNE METHODE DE REPRESENTATION DES TRANSITIONS QUI PERMET DE COMBINER DANS UNE PROPORTION QUELCONQUE LA REPRESENTATION PAR VECTEUR DE FONCTIONS ET LA REPRESENTATION PAR RELATION, PLUS COUTEUSE EN MEMOIRE MAIS PLUS RAPIDE. UN SECOND PROBLEME PRATIQUE EST LA DIFFICULTE DE SPECIFIER DANS LES LOGIQUES TEMPORELLES UTILISEES.

Book excerpt: A cause de la complexité croissante des systèmes sur puce (SoC), la vérification devient un aspect très important : 70 - 80% du coût de conception est alloué à cette tâche. Plus de 60% des projets de développement d'ASIC doivent être repris à cause des erreurs fonctionnelles, environ 50% des erreurs de conception étant situées au niveau du module. Dans le monde industriel, la vérification est souvent synonyme de simulation - une méthode de vérification naturelle pour les concepteurs, mais qui ne garantit pas l'absence d'erreurs. Une alternative est fournie par la vérification formelle qui prouve mathématiquement qu'un circuit satisfait une spécification. Dans cette thèse, on s'intéresse aux méthodes déductives basées sur la démonstration de théorèmes. La démonstration de théorèmes permet de vérifier formellement des descriptions matérielles de haut niveau et des systèmes réguliers ou très complexes, car la taille de données n'a plus d'importance. Par contre la modélisation de la description matérielle se fait directement en logique, ce qui rend l'accès difficile pour les concepteurs. Notre travail a pour but de faciliter l'introduction des outils de démonstration de théorèmes dans le flot de conception. Nous proposons une méthode automatique de traduction d'un circuit VHDL vers un modèle sémantique basé sur des équations récurrentes par rapport au temps qui peut être l'entrée de tout outil de démonstration de théorèmes et nous définissons une approche de vérification adaptée au modèle. Afin de valider notre proposition, nous avons choisi le démonstrateur ACL2 pour vérifier une bibliothèque de circuits de cryptographie.

Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Download or read book Certified Programming with Dependent Types written by Adam Chlipala and published by MIT Press. This book was released on 2013-12-06 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: A handbook to the Coq software for writing and checking mathematical proofs, with a practical engineering focus. The technology of mechanized program verification can play a supporting role in many kinds of research projects in computer science, and related tools for formal proof-checking are seeing increasing adoption in mathematics and engineering. This book provides an introduction to the Coq software for writing and checking mathematical proofs. It takes a practical engineering focus throughout, emphasizing techniques that will help users to build, understand, and maintain large Coq developments and minimize the cost of code change over time. Two topics, rarely discussed elsewhere, are covered in detail: effective dependently typed programming (making productive use of a feature at the heart of the Coq system) and construction of domain-specific proof tactics. Almost every subject covered is also relevant to interactive computer theorem proving in general, not just program verification, demonstrated through examples of verified programs applied in many different sorts of formalizations. The book develops a unique automated proof style and applies it throughout; even experienced Coq users may benefit from reading about basic Coq concepts from this novel perspective. The book also offers a library of tactics, or programs that find proofs, designed for use with examples in the book. Readers will acquire the necessary skills to reimplement these tactics in other settings by the end of the book. All of the code appearing in the book is freely available online.

Download or read book Symbolic Model Checking written by Kenneth L. McMillan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal verification means having a mathematical model of a system, a language for specifying desired properties of the system in a concise, comprehensible and unambiguous way, and a method of proof to verify that the specified properties are satisfied. When the method of proof is carried out substantially by machine, we speak of automatic verification. Symbolic Model Checking deals with methods of automatic verification as applied to computer hardware. The practical motivation for study in this area is the high and increasing cost of correcting design errors in VLSI technologies. There is a growing demand for design methodologies that can yield correct designs on the first fabrication run. Moreover, design errors that are discovered before fabrication can also be quite costly, in terms of engineering effort required to correct the error, and the resulting impact on development schedules. Aside from pure cost considerations, there is also a need on the theoretical side to provide a sound mathematical basis for the design of computer systems, especially in areas that have received little theoretical attention.

Download or read book Self Stabilizing Systems written by Sukumar Ghosh and published by Carleton University Press. This book was released on 1997 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self- governing control is a defining characteristic of autonomous computing machinery. Autonomy implies some degree of independence, and when a system's ability to achieve its mission is independent of how it is initialized, the system is self-stabilizing. Application of self-stabilization to system and network components is motivated by core concerns of fault-tolerance in distributed systems. Self-stabilization is a solution to problems of transient memory faults and systems with dynamic reconfigurations. Research in self-stabilization explores many of the classic themes of distributed computing (distributed graph algorithms, mutual exclusion, distributed agreement). Recent papers combine self-stabilization with traditional forms of fault-tolerance, consider methodological issues for the design of self-stabilizing systems, investigate randomized techniques, and apply stabilization to new networking models. The workshop brings together concerns from theory and practice of self-stabilization.

Download or read book Introduction to Distributed Self Stabilizing Algorithms written by Karine Altisen and published by Morgan & Claypool Publishers. This book was released on 2019-04-15 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims at being a comprehensive and pedagogical introduction to the concept of self-stabilization, introduced by Edsger Wybe Dijkstra in 1973. Self-stabilization characterizes the ability of a distributed algorithm to converge within finite time to a configuration from which its behavior is correct (i.e., satisfies a given specification), regardless the arbitrary initial configuration of the system. This arbitrary initial configuration may be the result of the occurrence of a finite number of transient faults. Hence, self-stabilization is actually considered as a versatile non-masking fault tolerance approach, since it recovers from the effect of any finite number of such faults in a unified manner. Another major interest of such an automatic recovery method comes from the difficulty of resetting malfunctioning devices in a large-scale (and so, geographically spread) distributed system (the Internet, Pair-to-Pair networks, and Delay Tolerant Networks are examples of such distributed systems). Furthermore, self-stabilization is usually recognized as a lightweight property to achieve fault tolerance as compared to other classical fault tolerance approaches. Indeed, the overhead, both in terms of time and space, of state-of-the-art self-stabilizing algorithms is commonly small. This makes self-stabilization very attractive for distributed systems equipped of processes with low computational and memory capabilities, such as wireless sensor networks. After more than 40 years of existence, self-stabilization is now sufficiently established as an important field of research in theoretical distributed computing to justify its teaching in advanced research-oriented graduate courses. This book is an initiation course, which consists of the formal definition of self-stabilization and its related concepts, followed by a deep review and study of classical (simple) algorithms, commonly used proof schemes and design patterns, as well as premium results issued from the self-stabilizing community. As often happens in the self-stabilizing area, in this book we focus on the proof of correctness and the analytical complexity of the studied distributed self-stabilizing algorithms. Finally, we underline that most of the algorithms studied in this book are actually dedicated to the high-level atomic-state model, which is the most commonly used computational model in the self-stabilizing area. However, in the last chapter, we present general techniques to achieve self-stabilization in the low-level message passing model, as well as example algorithms.
