• Sommario/riassunto: The design of code and cipher systems has undergone major changes in modern times. Powerful personal computers have resulted in an explosion of e-banking, e-commerce and e-mail, and as a consequence the encryption of communications to ensure security has become a matter of public interest and importance. This book describes and analyses many cipher systems ranging from the earliest and elementary to the more recent and sophisticated, such as RSA and ; DES, as well as wartime machines such as the ENIGMA and Hagelin, and ciphers used by spies. Security issues and possible methods of attack are discussed and illustrated by examples. The design of many systems involves advanced mathematical concepts and this is explained in detail in a major appendix. This book will appeal to anyone interested in codes and ciphers as used by private individuals, spies, governments and industry throughout history.

• Sommario/riassunto: Of the 218 letters, 126 belong to correspondence with the Imperial Count Ernst Christoph von Manteuffel, a dedicated patron of the supporters of Christian Wolff and the head of the Berlin chapter of the Society of Alethophiles. In Berlin and Leipzig great hopes were placed in the Prussian heir apparent Friedrich II, whom many saw a kind of Platonian "philosopher king" who would help elevate reason and Wolffian philosophy to new heights. The letters document the development of a rationalistic strain in Gottsched's sermons. They also provide insight into the satires of Wolff's opponents written
