This book focuses on security science and technology, data and information security, and mobile and network security for space-air-ground integrated networks (SAGINs). SAGIN are expected to play an increasingly important role in providing real-time, flexible, and integrated communication and data transmission services in an efficient manner. Today, SAGINs have been widely developed for a range of applications in navigation, environmental monitoring, traffic management, counter-terrorism, etc. However, security becomes a major concern, since the satellites, spacecrafts, and aircrafts are susceptible to a variety of traditional/specific network-based attacks, including eavesdropping, session hijacking, and illegal access. In this book, we review the theoretical foundations of SAGIN security. We also address a range of related security threats and provide cutting-edge solutions in the aspect of ground network security, airborne network security, space network security, and provide future trends in SAGIN security. The book goes from an introduction to the topic’s background, to a description of the basic theory, and then to cutting-edge technologies, making it suitable for readers at all levels including professional researchers and beginners. To gain the most from the book, readers should have taken prior courses in information theory, cryptography, network security, etc.

The papers are organized in topical sections on architecture and efficient networking mechanism; theories and methods of high speed transmission; and sparse characterization and fusion processing.
This book brings together papers presented at the 2016 International Conference on Communications, Signal Processing, and Systems, which provides a venue to disseminate the latest developments and to discuss the interactions and links between these multidisciplinary fields. Spanning topics ranging from communications to signal processing and systems, this book is aimed at undergraduate and graduate students in electrical engineering, computer science and mathematics, researchers and engineers from academia and industry as well as government employees (such as NSF, DOD and DOE).
(cont.) Additionally, innovative ways of using a space-based information network can revolutionize satellite communications and space missions. Applications include distributed computing in space, interoperable space communications, multiplatform distributed satellite communications, coherent distributed space sensing, multisensor data fusion, and restoration of disconnected global terrestrial networks after a disaster. Lastly, the consolidation of all the different communications assets into a horizontally integrated space-based network infrastructure calls for a space-based network backbone to be designed with a generic nature. A coherent infrastructure can satisfy the goals of interoperability, flexibility, scalability, and allows the system to be evolutionary. This transformational vision of a generic space-based information network allows for growth to accommodate civilian demands, lowers the price of entry for the commercial sector, and makes way for innovation to enhance and provide additional value to military systems.
The challenge of communication in planetary exploration has been unusual. The guidance and control of spacecraft depend on reliable communication. Scientific data returned to earth are irreplaceable, or replaceable only at the cost of another mission. In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Yet the limits must be approached warily, with reliability as well as channel capacity in mind. Further, the effects of small changes in the earth's atmosphere and the interplanetary plasma have small but important effects on propagation time and hence on the measurement of distance. Advances are almost incredible. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977. This improvement was attained through ingenious design based on the sort of penetrating analysis set forth in this book by engineers who took part in a highly detailed and amazingly successful pro gram. Careful observation and analysis have told us much about limitations on the accurate measurement of distance. It is not easy to get busy people to tell others clearly and in detail how they have solved important problems. Joseph H. Yuen and the other contribu tors to this book are to be commended for the time and care they have devoted to explicating one vital aspect of a great adventure of mankind.
Just as terrestrial networks have shifted to routed, message centric networks, the satellite networking regime is beginning to transition in the same manner. Based on established networking theories and unique orbital models, a satellite based communications network architecture is modeled that would fulfill the requirements of capacity, coverage and logistics for current and future military needs. Specifically, various satellite constellations and network characteristics are examined with a focus on how to enhance current methods of routing data in this environment. The authors explore how Social Networking theories can be applied to the routing decision making process in the space environment. Utilizing aspects of adaptation and the weak-tie relationship, an adaptive hybrid routing protocol model is proposed leveraging the predictability of orbital mechanics to increase performance and decrease network overhead.
