Applied Cryptography in Computer And Communications

This book provides a concise survey of principles and state-of-the-art techniques for secure group communications (SGC) over data networks. It offers an overview of secure algorithms and protocols for group communication linking areas such as applied cryptography and computer networking. Also included is a coverage of challenges in deploying secure group communication-based applications over wireless networks. These challenges include the limited computational power of mobile devices, susceptibility of wireless networks to intrusion and unauthorized access and mobility of nodes in a wireless ad-hoc network environment.

Secure Group Communications Over Data Networks provides a wealth of information for network architects, IT Professionals, computer scientists, and advanced students of computer science and computer engineering in the fields of networking, computer security and software applications development.

Hackers, IT professionals, and Infosec aficionados will find a gripping story that takes the reader on a global trip through the world of computer security exploits. One half massive case study, one half technical manual, Dissecting the Hack has it all - learn all about hacking tools and techniques and how to defend your network against threats.

Telecommunication has never been perfectly secure. The Cold War culture of recording devices in telephone receivers and bugged embassy offices has been succeeded by a post-9/11 world of NSA wiretaps and demands for data retention. Although the 1990s battle for individual and commercial freedom to use cryptography was won, growth in the use of cryptography has been slow.

This book provides a first course on lattices – mathematical objects pertaining to the realm of discrete geometry, which are of interest to mathematicians for their structure and, at the same time, are used by electrical and computer engineers working on coding theory and cryptography. The book presents both fundamental concepts and a wealth of applications, including coding and transmission over Gaussian channels, techniques for obtaining lattices from finite prime fields and quadratic fields, constructions of spherical codes, and hard lattice problems used in cryptography. The topics selected are covered in a level of detail not usually found in reference books. As the range of applications of lattices continues to grow, this work will appeal to mathematicians, electrical and computer engineers, and graduate or advanced undergraduate in these fields.
