This is a textbook for a course (or self-instruction) in cryptography with emphasis on algebraic methods. The first half of the book is a self-contained informal introduction to areas of algebra, number theory, and computer science that are used in cryptography. Most of the material in the second half - "hidden monomial" systems, combinatorial-algebraic systems, and hyperelliptic systems - has not previously appeared in monograph form. The Appendix by Menezes, Wu, and Zuccherato gives an elementary treatment of hyperelliptic curves. This book is intended for graduate students, advanced undergraduates, and scientists working in various fields of data security.

Does Chinese food taste the same in different parts of the world? What has happened to the Chinese diet in mainland China, Taiwan, Hong Kong and Macau? What has affected the foodways of Chinese communities in other Asian countries with large Chinese diasporic communities? What has made Chinese food popular in Australia, Indonesia, the Philippines and Japan? What has brought about the adoption and adaptation of western food and changes in Chinese diets in Hong Kong, Taiwan and Peking? By considering the practice of globalization, this volume of essays by well-known anthropologists from many locales in Asia, describes changes, variations and innovations to Chinese food in many parts of the world, paying particular attention to questions related to how foods are introduced, maintained, localised and reinvented according to changing lifestyles and social tastes. The book reviews and broadens classic social science theories about ethnic and social identity formation through the examination of Chinese food and eating habits in many locations. It reveals surprising changes and provides a powerful testimony to the impact of late twentieth-century globalization.

From the reviews: "This is a textbook in cryptography with emphasis on algebraic methods. It is supported by many exercises (with answers) making it appropriate for a course in mathematics or computer science. ...] Overall, this is an excellent expository text, and will be very useful to both the student and researcher."
