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.

With ever-increasing demands on capacity, quality of service, speed, and reliability, current Internet systems are under strain and under review. Combining contributions from experts in the field, this book captures the most recent and innovative designs, architectures, protocols, and mechanisms that will enable researchers to successfully build the next-generation Internet. A broad perspective is provided, with topics including innovations at the physical/transmission layer in wired and wireless media, as well as the support for new switching and routing paradigms at the device and sub-system layer. The proposed alternatives to TCP and UDP at the data transport layer for emerging environments are also covered, as are the novel models and theoretical foundations proposed for understanding network complexity. Finally, new approaches for pricing and network economics are discussed, making this ideal for students, researchers, and practitioners who need to know about designing, constructing, and operating the next-generation Internet.

Wavelength Division Multiplexed (WDM) optical networks are emerging as promising candidates for the infrastructure of the next-generation Internet. Such networks are envisaged for spanning local, metropolitan and wide geographical areas. WDM optical networks go beyond technologies such as Synchronous Optical Network (SONET) and Asynchronous Transfer Mode (ATM) in realizing the full potential of the optical medium. From passive star coupler-based broadcast optical networks to switch-based optical wavelength-routed networks, the text covers a wide range of available technologies and designs for proposed network architectures. The author investigates the impact of physical-layer issues on the design of such WDM-based optical networks. In particular, this work presents a sampling of problems such as amplifier placement and optimization, sharing and minimization of wavelength converter usage, and bit-error rate (BER)-based all-admission in WDM optical networks and proposes novel solutions. Efficient algorithms are described which significantly improve the cost-effectiveness of WDM networks.Design of Optical WDM Networks: This work is targeted towards practitioners and researchers in the field of optical networks and WDM as well as students interested in the future of networking and telecommunications. "The field of optical WDM networks has experienced widespread attention and growth in recent years. This book, I believe, will be a welcome addition to the literature focusing on this exciting technology!" (From the Foreword by Professor Biswanath Mukherjee University of California).
