The first edition of this award-winning book attracted a wide audience. This second edition is both a joy to read and a useful classroom tool. Unlike traditional textbooks, it requires no mathematical prerequisites and can be read around the mathematics presented. If used as a textbook, the mathematics can be prioritized, with a book both students and instructors will enjoy reading. Secret History: The Story of Cryptology, Second Edition incorporates new material concerning various eras in the long history of cryptology. Much has happened concerning the political aspects of cryptology since the first edition appeared. The still unfolding story is updated here. The first edition of this book contained chapters devoted to the cracking of German and Japanese systems during World War II. Now the other side of this cipher war is also told, that is, how the United States was able to come up with systems that were never broken. The text is in two parts. Part I presents classic cryptology from ancient times through World War II. Part II examines modern computer cryptology. With numerous real-world examples and extensive references, the author skillfully balances the history with mathematical details, providing readers with a sound foundation in this dynamic field.

Representing a crucial intervention in the history of internationalism, transnationalism and global history, this edited collection examines a variety of international movements, organisations and projects developed in Europe or by Europeans over the course of the 20th century. Reacting against the old Eurocentricism, much of the scholarship in the field has refocussed attention on other parts of the globe. This volume attempts to rethink the role played by ideas, people and organisations originating or located in Europe, including some of their consequential global impact. The chapters cover aspects of internationalism such as the importance of language, communication and infrastructures of internationalism; ways of grappling with the history of internationalism as a lived experience; and the roles of European actors in the formulation of different and often competing models of internationalism. It demonstrates that the success and failure of international programmes were dependent on participants' ability to communicate across linguistic but also political, cultural and economic borders. By bringing together commonly disconnected strands of European history and 'history from below', this volume rebalances and significantly advances the field, and promotes a deeper understanding of internationalism in its many historical guises. The volume is conceived as a way of thinking about internationalism that is relevant not just to scholars of Europe, but to international and global history more generally.
What started out as a minor Project in 1987, blew out like the national debt so with all this accumulated info, it seemed worthwhile to produce the first book, here now is the Latest Online Edition. The sources and references have been many and varied and although the utmost care was taken, the Lists are far from complete and may contain errors. The original Codes etc were designed principally for marine use as this was the field in which radio was initially developed. The majority retain this influence but many have been modified and modernized to cover land and air applications. Technical terms have also varied as technology has changed however most abbreviations of the computer age have been omitted. These are specialist terms of that mode, not often encountered in telegraphy.
