Book Synopsis Challenges of Software Verification by : Vincenzo Arceri
Download or read book Challenges of Software Verification written by Vincenzo Arceri and published by Springer Nature. This book was released on 2023-09-04 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview about the open challenges in software verification. Software verification is a branch of software engineering aiming at guaranteeing that software applications satisfy some requirements of interest. Over the years, the software verification community has proposed and considered several techniques: abstract interpretation, data-flow analysis, type systems, model checking are just a few examples. The theoretical advances have been always motivated by practical challenges that have led to an equal evolution of both these sides of software verification. Indeed, several verification tools have been proposed by the research community and any software application, in order to guarantee that certain software requirements are met, needs to integrate a verification phase in its life cycle, independently of the context of application or software size. This book is aimed at collecting contributions discussing recent advances in facing open challenges in software verification, relying on a broad spectrum of verification techniques. This book collects contributions ranging from theoretical to practical arguments, and it is aimed at both researchers in software verification and their practitioners.

Book Synopsis Static Analysis of JavaScript Programs for Bug Detection by :
Download or read book Static Analysis of JavaScript Programs for Bug Detection written by and published by . This book was released on 2017 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: JavaScript is an object-oriented language that was originally developed to make web pages more attractive. Gradually, its features became a good fit for non-browser applications. For a developer, JavaScript might not be the first choice of language. It supports first class functions, meaning that a function can appear anywhere one might normally pass values or objects. JavaScript allows the code to be dynamically evaluated through the eval function. Most of all, it is dynamically typed, which means that a variable can change types during a program execution. The above-mentioned JavaScript features make it flexible to use but also open doors to many vulnerabilities and programming errors. Although a lot of effort has been dedicated to the design and implementation of JavaScript static analyzers, a lot remains to be done. Tools to aid developers are still at an early stage. Those include editor support such as auto-completion and debugging as well as static analysis for code quality and bug detection. A type error in JavaScript occurs when calling a non-function value as a function or accessing or updating a property of null/undefined. Unlike other programming errors like reading an absent property of an object, a type error can cause a program to crash or malfunction. Motivated by the severity of type errors, we proposed solutions to enhance static analyzers detecting type errors. We introduced an extended domain of intervals to improve the precision of existing static analyzers. That extended domain of intervals was used in an existing static analyzer called JSAI [47] and was able to reduce the number of false positives by 39% [81]. With JavaScript numbers following the IEEE-754 standard, we later redesigned the extended domain of intervals to conform to standard with IEEE-754 floating point bounds and were able to further improve the precision in some benchmark programs [82]. Following this, we introduced a range assertion language for JavaScript programs. Unlike Java, JavaScript does not support assertions and developers have to write their own assertion functions. The range assertion language was motivated by the fact that, when accessing a non-existent index in an array in JavaScript, the arrayIndexOutOfBound exception is not thrown. Instead, the array access operation fails silently and an undefined value is returned. It is important to track such silent errors because the returned value that is undefined could cause some type errors in the remaining execution of a program. The range assertions are automatically checked during the execution of a program. Our evaluation reported one confirmed violation in seven benchmark programs analyzed. Following the range assertions, we proposed a novel abstract string domain for static conventionality analysis of JavaScript arrays. A JavaScript array object is just like any other kind of object except that it has a length property that is automatically updated. A conventional array is an array that does not have properties other than indices and length. Do JavaScript programmers use arrays conventionally just like in other object oriented languages? Do they use arrays like regular objects? We proposed a static conventionality analysis for JavaScript to help us to find answers to these questions. Conventionality analysis can be useful for program understanding and optimization. Our experiments on a set of 98 benchmark programs show that arrays are used in a conventional way in 95% of the benchmark programs. This thesis ends with a summary of the main contributions and discusses future work and research directions.

Download or read book Development of Safety-Critical Systems written by Gopinath Karmakar and published by Springer Nature. This book was released on 2023-10-09 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides professionals and students with practical guidance for the development of safety-critical computer-based systems. It covers important aspects ranging from complying with standards and guidelines to the necessary software development process and tools, and also techniques pertaining to model-based application development platforms as well as qualified programmable controllers. After a general introduction to the book’s topic in chapter 1, chapter 2 discusses dependability aspects of safety systems and how architectural design at the system level helps deal with failures and yet achieves the targeted dependability attributes. Chapter 3 presents the software development process which includes verification and validation at every stage, essential to the development of software for systems performing safety functions. It also explains how the process helps in developing a safety case that can be independently verified and validated. The subsequent chapter 4 presents some important standards and guidelines, which apply to different industries and in different countries. Chapter 5 then discusses the steps towards complying with the standards at every phase of development. It offers a guided tour traversing the path of software qualification by exploring the necessary steps towards achieving the goal with the help of case studies. Chapter 6 highlights the application of formal methods for the development of safety systems software and introduces some available notations and tools which assist the process. Finally, chapter 7 presents a detailed discussion on the importance and the advantages of qualified platforms for safety systems application development, including programmable controller (PLC) and formal model-based development platforms. Each chapter includes case studies illustrating the subject matter. The book is aimed at both practitioners and students interested in the art and science of developing computer-based systems for safety-critical applications. Both audiences will get insights into the tools and techniques along with the latest developments in the design, analysis and qualification, which are constrained by the regulatory and compliance requirements mandated by the applicable guides and standards. It also addresses the needs of professionals and young graduates who specialize in the development of necessary tools and qualified platforms.

Book Synopsis Dependable Embedded Systems by : Jörg Henkel
Download or read book Dependable Embedded Systems written by Jörg Henkel and published by Springer Nature. This book was released on 2020-12-09 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book introduces readers to many new techniques for enhancing and optimizing reliability in embedded systems, which have emerged particularly within the last five years. This book introduces the most prominent reliability concerns from today’s points of view and roughly recapitulates the progress in the community so far. Unlike other books that focus on a single abstraction level such circuit level or system level alone, the focus of this book is to deal with the different reliability challenges across different levels starting from the physical level all the way to the system level (cross-layer approaches). The book aims at demonstrating how new hardware/software co-design solution can be proposed to ef-fectively mitigate reliability degradation such as transistor aging, processor variation, temperature effects, soft errors, etc. Provides readers with latest insights into novel, cross-layer methods and models with respect to dependability of embedded systems; Describes cross-layer approaches that can leverage reliability through techniques that are pro-actively designed with respect to techniques at other layers; Explains run-time adaptation and concepts/means of self-organization, in order to achieve error resiliency in complex, future many core systems.
Download or read book Dynamic Logic written by David Harel and published by MIT Press. This book was released on 2000-09-29 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive introduction to Dynamic Logic. Among the many approaches to formal reasoning about programs, Dynamic Logic enjoys the singular advantage of being strongly related to classical logic. Its variants constitute natural generalizations and extensions of classical formalisms. For example, Propositional Dynamic Logic (PDL) can be described as a blend of three complementary classical ingredients: propositional calculus, modal logic, and the algebra of regular events. In First-Order Dynamic Logic (DL), the propositional calculus is replaced by classical first-order predicate calculus. Dynamic Logic is a system of remarkable unity that is theoretically rich as well as of practical value. It can be used for formalizing correctness specifications and proving rigorously that those specifications are met by a particular program. Other uses include determining the equivalence of programs, comparing the expressive power of various programming constructs, and synthesizing programs from specifications. This book provides the first comprehensive introduction to Dynamic Logic. It is divided into three parts. The first part reviews the appropriate fundamental concepts of logic and computability theory and can stand alone as an introduction to these topics. The second part discusses PDL and its variants, and the third part discusses DL and its variants. Examples are provided throughout, and exercises and a short historical section are included at the end of each chapter.
