The ubiquitous nature of mobile and pervasive computing has begun to reshape and complicate our notions of space, time, and identity. In this collection, over thirty internationally recognized contributors reflect on ubiquitous computing s implications for the ways in which we interact with our environments, experience time, and develop identities individually and socially. Interviews with working media artists lend further perspectives on these cultural transformations. Drawing on cultural theory, new media art studies, human-computer interaction theory, and software studies, this...

This work adds a new perspective to the stream of organizational IT security risk management literature, one that sheds light on the importance of IT security risk perceptions. Based on a large-scale empirical study of Cloud providers located in North America, the study reveals that in many cases, the providers' decision makers significantly underestimate their services' IT security risk exposure, which inhibits the implementation of necessary safeguarding measures. The work also demonstrates that even though the prevalence of IT security risk concerns in Cloud adoption is widely...

Why does information technology disappoint or enslave us? Why do so many information systems projects collapse? How can we do better? There are many technical, social, economic and other aspects to consider. How do we ensure we take all these into account as we research ITC or employ them? ICT affects our lives and world more profoundly than ever before. How may we understand it? This book employs philosophy to lay foundations for understanding the complexity of ICT, in five areas:

• The nature of information and computers, and artificial intelligence;
...

The two-volume set LNCS 9452 and 9453 constitutes the refereed proceedings of the 21st International Conference on the Theory and Applications of Cryptology and Information Security, ASIACRYPT 2015, held in Auckland, New Zealand, in November/December 2015.

The 64 revised full papers and 3 invited talks presented were carefully selected from 251 submissions. They are organized in topical sections on indistinguishability obfuscation; PRFs and hashes; discrete logarithms and number theory; signatures; multiparty computation; public key encryption; ABE and IBE; zero-knowledge; attacks...

The first part of this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security...

This textbook effectively builds a bridge from basic number theory to recent advances in applied number theory. It presents the first unified account of the four major areas of application where number theory plays a fundamental role, namely cryptography, coding theory, quasi-Monte Carlo methods, and pseudorandom number generation, allowing the authors to delineate the manifold links and interrelations between these areas.

Number theory, which Carl-Friedrich Gauss famously dubbed the queen of mathematics, has always been considered a very beautiful field of mathematics, producing...

No matter what DBMS you are using--Oracle, DB2, SQL Server, MySQL, PostgreSQL--misunderstandings can always arise over the precise meanings of terms, misunderstandings that can have a serious effect on the success of your database projects. For example, here are some common database terms: attribute, BCNF, consistency, denormalization, predicate, repeating group, join dependency. Do you know what they all mean? Are you sure?

The New Relational Database Dictionary defines all of these terms and many, many more. Carefully reviewed...

This book constitutes the refereed proceedings of the Cryptographer's Track at the RSA Conference 2016, CT-RSA 2016, held in San Francisco, CA, USA, in February/March 2016.

The 26 papers presented in this volume were carefully reviewed and selected from 76 submissions. The focus of the track is on following subjects: secure key exchange schemes, authenticated encryption, searchable symmetric encryption, digital signatures with new functionality, secure multi party computation, how to verify procedures, side-channel attacks on elliptic curve cryptography, hardware attacks and...
