This is the first comprehensive text to cover finite linear spaces. It contains all the important results that have been published up to the present day and is designed to be used not only as a resource for researchers in this and related areas but also as a graduate level text. In eight chapters, the authors introduce and review fundamental results and go on to cover the major areas of interest in linear spaces. A combinatorial approach is used for the greater part of the book, but in the final chapter recent advances in group theory relating to finite linear spaces are presented. At the end...

Cryptology, the art and science of 'secret writing', provides ideal methods to solve the problems of transmitting information secretly and securely. The first half of this book studies and analyzes classical cryptosystems. The second half looks at the exciting new directions of public-key cryptology. The book is fun to read, and the author presents the material clearly and simply. Many exercises and references accompany each chapter.
