Network Aware Security For Group Communications

This book aims to fill a growing need in the research community for a reference that describes the state-of-the-art in securing group communications. It focuses on tailoring the security solution to the underlying network architecture (such as the wireless cellular network or the ad hoc/sensor network), or to the application using the security methods (such as multimedia multicasts).

The ubiquitous nature of the Internet is enabling a new generation of - pUcations to support collaborative work among geographically distant users. Security in such an environment is of utmost importance to safeguard the pri vacy of the communication and to ensure the integrity of the applications. 'Secure group communications' (SGC) refers to a scenario in which a group of participants can receive and send messages to group members, in a way that outsiders are unable to glean any information even when they are able to intercept the messages. SGC is becoming extremely important for researchers and practitioners because many applications that require SGC are now widely used, such as teleconferencing, tele-medicine, real-time information services, distributed interactive simulations, collaborative work, grid computing, and the deployment of VPN (Virtual Private Networks). Even though considerable research accomplishments have been achieved in SGC, few books exist on this very important topic. The purpose of this book is to provide a comprehensive survey of principles and state-of-the-art techniques for secure group communications over data net works. The book is targeted towards practitioners, researchers and students in the fields of networking, security, and software applications development. The book consists of 7 chapters, which are listed and described as follows.

While wireless technologies continue to provide an array of new challenges and multi-domain applications for business processes and solutions, there still remains to be a comprehensive understanding of its various dimensions and environments. Security, Design, and Architecture for Broadband and Wireless Network Technologies provides a discussion on the latest research achievements in wireless networks and broadband technology. Highlighting new trends, applications, developments, and standards, this book is essential for next generation researchers and practitioners in the ICT field.

The conference on network security and communication engineering is meant to serve as a forum for exchanging new developments and research progresss between scholars, scientists and engineers all over the world and providing a unique opportunity to exchange information, to present the latest results as well as to review the relevant issues on

CollaborateCom is an annual international forum for dissemination of original ideas and research results in collaborative computing networks, systems, and applications. A major goal and feature of CollaborateCom is to bring researchers from networking, systems, CSCW, collaborative learning, and collaborative education areas - gether. CollaborateCom 2008 held in Orlando, Florida, was the fourth conference of the series and it reflects the accelerated growth of collaborative computing, both as research and application areas. Concretely, recent advances in many computing fields have contributed to the growing interconnection of our world, including multi-core architectures, 3G/4G wi- less networks, Web 2. 0 technologies, computing clouds, and software as a service, just to mention a few. The potential for collaboration among various components has - ceeded the current capabilities of traditional approaches to system integration and interoperability. As the world heads towards unlimited connectivity and global c- puting, collaboration becomes one of the fundamental challenges for areas as diverse as eCommerce, eGovernment, eScience, and the storage, management, and access of information through all the space and time dimensions. We view collaborative c- puting as the glue that brings the components together and also the lubricant that makes them work together. The conference and its community of researchers dem- strate the concrete progress we are making towards this vision. The conference would not have been successful without help from so many people.

Although the information and communication technology (ICT) industry accounted for only 2 percent of global greenhouse gas emissions in 2007, the explosive increase in data traffic brought about by a rapidly growing user base of more than a billion wireless subscribers is expected to nearly double that number by 2020. It is clear that now is the time to rethink how we design and build our networks. Green Networking and Communications: ICT for Sustainability brings together leading academic and industrial researchers from around the world to discuss emerging developments in energy-efficient networking and communications. It covers the spectrum of research subjects, including methodologies and architectures for energy efficiency, energy-efficient protocols and networks, energy management, smart grid communications, and communication technologies for green solutions. Examines foraging-inspired radio-communication energy management for green multi-radio networks Considers a cross-layer approach to the design of energy-efficient wireless access networks Investigates the interplay between cooperative device-to-device communications and green LTE cellular networks Considers smart grid energy procurement for green LTE cellular networks Details smart grid networking protocols and standards Considering the spectrum of energy-efficient network components and approaches for reducing power consumption, the book is organized into three sections: Energy Efficiency and Management in Wireless Networks, Cellular Networks, and Smart Grids. It addresses many open research challenges regarding energy efficiency for IT and for wireless sensor networks, including mobile and wireless access networks, broadband access networks, home networks, vehicular networks, intelligent future wireless networks, and smart grids. It also examines emerging standards for energy-efficient protocols. Since ICT technologies touch on nearly all sectors of the economy, the concepts presented in this text offer you the opportunity to make a substantial contribution to the reduction of global greenhouse gas emissions.
