Digital Signatures
by Jonathan KatzAs a beginning graduate student, I recall being frustrated by a general lack of acces sible sources from which I could learn about (theoretical) cryptography. I remember wondering: why aren’t there more books presenting the basics of cryptography at an introductory level? Jumping ahead almost a decade later, as a faculty member my graduate students now ask me: what is the best resource for learning about (various topics in) cryptography? This monograph is intended to serve as an answer to these 1 questions — at least with regard to digital signature schemes. Given the above motivation, this book has been written with a beginninggraduate student in mind: a student who is potentially interested in doing research in the ?eld of cryptography, and who has taken an introductory course on the subject, but is not sure where to turn next. Though intended primarily for that audience, I hope that advanced graduate students and researchers will ?nd the book useful as well. In addition to covering various constructions of digital signature schemes in a uni?ed framework, this text also serves as a compendium of various “folklore” results that are, perhaps, not as well known as they should be. This book could also serve as a textbook for a graduate seminar on advanced cryptography; in such a class, I expect the entire book could be covered at a leisurely pace in one semester with perhaps some time left over for excursions into related topics.
Digital Spaces of Civic Communication: The Practices and Interfaces of Online Commenting
by Anne MollenThis book addresses the socio-technical constitution of civic communication in increasingly digital democracies. Despite problematic phenomena like hate speech in online commenting, it argues that citizens’ potential for resisting technological inscriptions in digital media remains a fundamental democratic right. While producers inscribe anticipations for how people should be discussing political issues into commenting interfaces, citizens still resist these technological inscriptions in their commenting practices. This dialectic interrelation between interfaces and practices highlights the inadequacy of purely technological solutions for undemocratic tendencies in digital media.

Digital Storytelling, Applied Theatre, & Youth: Performing Possibility
by Megan AlrutzDigital Storytelling, Applied Theatre, & Youth argues that theatre artists must re-imagine how and why they facilitate performance practices with young people. Rapid globalization and advances in media and technology continue to change the ways that people engage with and understand the world around them. Drawing on pedagogical, aesthetic, and theoretical threads of applied theatre and media practices, this book presents practitioners, scholars, and educators with innovative approaches to devising and performing digital stories. This book offers the first comprehensive examination of digital storytelling as an applied theatre practice. Alrutz explores how participatory and mediated performance practices can engage the wisdom and experience of youth; build knowledge about self, others and society; and invite dialogue and deliberation with audiences. In doing so, she theorizes digital storytelling as a site of possibility for critical and relational practices, feminist performance pedagogies, and alliance building with young people.

Digital Synthesizers and Transmitters for Software Radio
by Jouko VankkaThe approach adopted in Digital Synthesizers and Transmitters for Software Radio will provide an understanding of key areas in the field of digital synthesizers and transmitters. It is easy to include different digital techniques in the digital synthesizers and transmitters by using digital signal processing methods, because the signal is in digital form. By programming the digital synthesizers and transmitters, adaptive channel bandwidths, modulation formats, frequency hopping and data rates are easily achieved. Techniques such as digital predistortion for power amplifier linearization, digital compensation methods for analog I/Q modulator nonlinearities and digital power control and ramping are presented in this book. The flexibility of the digital synthesizers and transmitters makes them ideal as signal generators for software radio. Software radios represent a major change in the design paradigm for radios in which a large portion of the functionality is implemented through programmable signal processing devices, giving the radio the ability to change its operating parameters to accommodate new features and capabilities. A software radio approach reduces the content of radio frequency (RF) and other analog components of traditional radios and emphasizes digital signal processing to enhance overall transmitter flexibility. Software radios are emerging in commercial and military infrastructure.
Digital System Design - Use of Microcontroller
by Shenouda Dawoud R. PeplowEmbedded systems are today, widely deployed in just about every piece of machinery from toasters to spacecraft. Embedded system designers face many challenges. They are asked to produce increasingly complex systems using the latest technologies, but these technologies are changing faster than ever. They are asked to produce better quality designs with a shorter time-to-market. They are asked to implement increasingly complex functionality but more importantly to satisfy numerous other constraints. To achieve the current goals of design, the designer must be aware with such design constraints and more importantly, the factors that have a direct effect on them.One of the challenges facing embedded system designers is the selection of the optimum processor for the application in hand; single-purpose, general-purpose or application specific. Microcontrollers are one member of the family of the application specific processors.The book concentrates on the use of microcontroller as the embedded system?s processor, and how to use it in many embedded system applications. The book covers both the hardware and software aspects needed to design using microcontroller.The book is ideal for undergraduate students and also the engineers that are working in the field of digital system design.Contents• Preface;• Process design metrics;• A systems approach to digital system design;• Introduction to microcontrollers and microprocessors;• Instructions and Instruction sets;• Machine language and assembly language;• System memory; Timers, counters and watchdog timer;• Interfacing to local devices / peripherals;• Analogue data and the analogue I/O subsystem;• Multiprocessor communications;• Serial Communications and Network-based interfaces.

Digital Technologies and Public Procurement: Gatekeeping and Experimentation in Digital Public Governance
by Albert Sanchez-GraellsThe digital transformation of the public sector has accelerated. States are experimenting with technology, seeking more streamlined and efficient digital government and public services. However, there are significant concerns about the risks and harms to individual and collective rights under new modes of digital public governance. Several jurisdictions are attempting to regulate digital technologies, especially artificial intelligence, however regulatory effort primarily concentrates on technology use by companies, not by governments. The regulatory gap underpinning public sector digitalisation is growing. As it controls the acquisition of digital technologies, public procurement has emerged as a 'regulatory fix' to govern public sector digitalisation. It seeks to ensure through its contracts that public sector digitalisation is trustworthy, ethical, responsible, transparent, fair, and (cyber) safe. However, in Digital Technologies and Public Procurement: Gatekeeping and Experimentation in Digital Public Governance, Albert Sanchez-Graells argues that procurement cannot perform this gatekeeping role effectively. Through a detailed case study of procurement digitalisation as a site of unregulated technological experimentation, he demonstrates that relying on 'regulation by contract' creates a false sense of security in governing the transition towards digital public governance. This leaves the public sector exposed to the 'policy irresistibility' that surrounds hyped digital technologies. Bringing together insights from political economy, public policy, science, technology, and legal scholarship, this thought-provoking book proposes an alternative regulatory approach and contributes to broader debates of digital constitutionalism and digital technology regulation.
