The First Enigma Codebreaker is the story of a man who started a revolution in cryptology and the conflict between man and machine. This is a powerful story of the life of Marian Rejewski and how history can affect individual lives, presented to the public for the first time. This examination of how Marian Rejewski changed the course of cryptology is of great interest to everyone from the avid historian to Hollywood film producers and all those in-between. As Gawlowski’s biography shows, Rejewski was an unassuming man who used his mathematical, skills as well as his extensive linguistic abilities, to start cracking the Enigma code before passing the baton on to the now renowned Alan Turing. This is a fascinating, human story about the man Marian Rejewski, which also ties up the loose threads of the Enigma story and shows the importance of the Polish involvement in that process. The First Enigma Codebreaker looks at those involved in cracking the Enigma and also takes a look at an aspect that has rarely been discussed in great detail, the story of Marian Rejewski himself, and how he endured life in post-war Communist Poland shining a light on situations such as how Rejewski managed to decode the machine, what happened to him during the Second World War, and the price he had to pay during the post war period.

A lucid guide to abstract algebra, this comprehensive textbook provides in depth coverage for upper undergraduate students.

From the exciting history of its development in ancient times to the present day, Introduction to Cryptography with Mathematical Foundations and Computer Implementations provides a focused tour of the central concepts of cryptography. Rather than present an encyclopedic treatment of topics in cryptography, it delineates cryptographic concepts in chronological order, developing the mathematics as needed. Written in an engaging yet rigorous style, each chapter introduces important concepts with clear definitions and theorems. Numerous examples explain key points while figures and tables help illustrate more difficult or subtle concepts. Each chapter is punctuated with "Exercises for the Reader;" complete solutions for these are included in an appendix. Carefully crafted exercise sets are also provided at the end of each chapter, and detailed solutions to most odd-numbered exercises can be found in a designated appendix. The computer implementation section at the end of every chapter guides students through the process of writing their own programs. A supporting website provides an extensive set of sample programs as well as downloadable platform-independent applet pages for some core programs and algorithms. As the reliance on cryptography by business, government, and industry continues and new technologies for transferring data become available, cryptography plays a permanent, important role in day-to-day operations. This self-contained sophomore-level text traces the evolution of the field, from its origins through present-day cryptosystems, including public key cryptography and elliptic curve cryptography.

Mathematics has for centuries been stimulated, financed and credited by military purposes. Some mathematical thoughts and mathematical technology have also been vital in war. During World War II mathematical work by the Anti-Hitler coalition was part of an aspiration to serve humanity and not help destroy it. At present, it is not an easy task to view the bellicose potentials of mathematics in a proper perspective. The book presents historical evidence and recent changes in the interaction between mathematics and the military. It discusses the new mathematically enhanced development of military technology which seems to have changed the very character of modern warfare.

The Proceedings contain twenty selected, refereed contributions arising from the International Conference on Public-Key Cryptography and Computational Number Theory held in Warsaw, Poland, on September 11-15, 2000. The conference, attended by eightyfive mathematicians from eleven countries, was organized by the Stefan Banach International Mathematical Center. This volume contains articles from leading experts in the world on cryptography and computational number theory, providing an account of the state of research in a wide variety of topics related to the conference theme. It is dedicated to the memory of the Polish mathematicians Marian Rejewski (1905-1980), Jerzy Róøycki (1909-1942) and Henryk Zygalski (1907-1978), who deciphered the military version of the famous Enigma in December 1932 January 1933. A noteworthy feature of the volume is a foreword written by Andrew Odlyzko on the progress in cryptography from Enigma time until now.

In this World War II military history, Rommel's army is a day from Cairo, a week from Tel Aviv, and the SS is ready for action. Espionage brought the Nazis this far, but espionage can stop them—if Washington wakes up to the danger. As World War II raged in North Africa, General Erwin Rommel was guided by an uncanny sense of his enemies' plans and weaknesses. In the summer of 1942, he led his Axis army swiftly and terrifyingly toward Alexandria, with the goal of overrunning the entire Middle East. Each step was informed by detailed updates on British positions. The Nazis, somehow, had a source for the Allies' greatest secrets. Yet the Axis powers were not the only ones with intelligence. Brilliant Allied cryptographers worked relentlessly at Bletchley Park, breaking down the extraordinarily complex Nazi code Enigma. From decoded German messages, they discovered that the enemy had a wealth of inside information. On the brink of disaster, a fevered and high-stakes search for the source began. War of Shadows is the cinematic story of the race for information in the North African theater of World War II, set against intrigues that spanned the Middle East. Years in the making, this book is a feat of historical research and storytelling, and a rethinking of the popular narrative of the war. It portrays the conflict not as an inevitable clash of heroes and villains but a spiraling series of failures, accidents, and desperate triumphs that decided the fate of the Middle East and quite possibly the outcome of the war.

Ethics and Human Behaviour in ICT Development discusses ethics in a professional context and encourages readers to self-assessment of their own behaviour. It provides thought-provoking accounts of the little-known early history of technological development in information and communication technology (ICT) and the automation industry in Poland, with a focus on Wroclaw. The book provides a framework for understanding the relationship between ethics and behaviour, and analyses critically ethical and behavioural issues in challenging workplaces and social contexts. It includes: case studies from around the world, especially Poland, which illustrate the relationships between human behaviour and ethics; biographies of successful Polish ICT and automation leading designers; analysis of case studies of human behaviour and ethics in challenging industrial development and other environments; and illustrative practical applications alongside the theory of human behaviour and ethics. The authors demonstrate the ingenuity of the early Polish designers, programmers and other specialists in overcoming the shortage of components caused by import embargoes to enable Poland to develop its own computer industry. An example of this is Elwro, formerly the largest manufacturer of computers in Poland. The discussion of its growth illustrates the potential of human creativity to overcome problems. The discussion of its fall highlights the importance of ethical approaches to technology transfer and the dangers of a colonialist mentality. The book is designed for engineers, computer scientists, researchers and professionals alike, as well as being of interest for those broadly concerned with ethics and human behaviour.
