This is the first book, to the best of my knowledge, which bridges two disjoint topics, optical networks and network security. It provides a comprehensive treatment of the next generation optical network and a comprehensive treatment of cryptographic algorithms, the quantum optical network, including advanced topics such as teleponation, and how detection and countermeasure strategies may be used. Therefore, we believe that this book differentiates from many others and presents a holistic approach to the treatment of secure optical networks, including fiber to the home (FTTH) and free space optical (FSO).
