RC4 Stream Cipher and Its Variants is the first book to fully cover the popular software stream cipher RC4. With extensive expertise in stream cipher cryptanalysis and RC4 research, the authors focus on the analysis and design issues of RC4. They also explore variants of RC4 and the eSTREAM finalist HC-128.

After an introduction to the vast field of cryptology, the book reviews hardware and software stream ciphers and describes RC4. It presents a theoretical analysis of RC4 KSA, discussing biases of the permutation bytes toward secret key bytes and absolute...

This book explores the political process behind the construction of cyber-threats as one of the quintessential security threats of modern times in the US.

Myriam Dunn Cavelty posits that cyber-threats are definable by their unsubstantiated nature. Despite this, they have been propelled to the forefront of the political agenda. Using an innovative theoretical approach, this book examines how, under what conditions, by whom, for what reasons, and with what impact cyber-threats have been moved on to the political agenda. In particular, it analyses how governments have used threat...

First developed in the early 1980s by Lenstra, Lenstra, and Lovasz, the LLL algorithm was originally used to provide a polynomial-time algorithm for factoring polynomials with rational coefficients. It very quickly became an essential tool in integer linear programming problems and was later adapted for use in cryptanalysis. This book provides an introduction to the theory and applications of lattice basis reduction and the LLL algorithm. With numerous examples and suggested exercises, the text discusses various applications of lattice basis reduction to cryptography, number theory,...

To grasp the importance of emergency notification, imagine this scenario: A shooter is on the loose at a college campus. Chaos reigns. To contain the situation, campus personnel need to communicate immediately and efficiently, not only with the students, faculty, and staff, but also the local police, federal law enforcement, and media. Effective emergency notification makes things "right," it allows the right message to reach the right people at the right time--facilitating the right response. "Emergency Notification" explains how.

Now more than ever before, today s schools are hazard zones. Students are vulnerable to attack from other students and random individuals who may appear to be harmless on the surface or who may be sending out warning signals. Either way, to save their lives or protect themselves from injury, they must be prepared. Now in its second edition, Staying Safe at School is a guidebook that every parent and school administrator should make available to students. Concise and practical, this book will show teenagers how to:

• Perform a risk assessment to...

Developed from the author s popular graduate-level course, Computational Number Theory presents a complete treatment of number-theoretic algorithms. Avoiding advanced algebra, this self-contained text is designed for advanced undergraduate and beginning graduate students in engineering. It is also suitable for researchers new to the field and practitioners of cryptography in industry.

Requiring no prior experience with number theory or sophisticated algebraic tools, the book covers many computational aspects of number theory and highlights important and...

A well-rounded, accessible exposition of honeypots in wired and wireless networks, this book addresses honeypots from a variety of perspectives. Case studies enhance the practical understanding of the subject along with strong theoretical foundation. The book covers the latest technology in information security and honeypots, including honeytokens, honeynets and honeyfarms. Topics include denial of service, virus, worms, phishing, and elaborates on virtual honeypots and forensics. Practical implementations as well as current state of research are discussed.
