About Invitation To Cryptology
Product Description For a one-semester undergraduate-level course in Cryptology, Mathematics, or Computer Science. Designed for either the intelligent freshman (good at math) or for a low-level junior year first course, Cryptology introduces a wide range of up-to-date cryptological concepts along with the mathematical ideas that are behind them. The new and old are organized around a historical framework. A variety of mathematical topics that are germane to cryptology (e.g., modular arithmetic, Boolean functions, complexity theory, etc.) are developed, but they do not overshadow the main focus of the text. Unlike other texts in this field, Cryptology brings students directly to concepts of classical substitutions and transpositions and issues in modern cryptographic methods. From the Back Cover This book introduces a wide range of up-to-date cryptological concepts along with the mathematical ideas that are behind them. The new and old are organized around a historical framework. A variety of mathematical topics that are germane to cryptology (e.g., modular arithmetic, Boolean functions, complexity theory, etc.) are developed, but they do not overshadow the main focus of the book. Chapter topics cover origins, examples, and ideas in cryptology; classical cryptographic techniques; symmetric computer-based cryptology; public-key cryptography; and present practice, issues, and the future. For individuals seeking an up-close and accurate idea of how current-day cryptographic methods work. Excerpt. © Reprinted by permission. All rights reserved. In 1994, my colleague Terri Lindquester had a pedagogical inspiration: to teach cryptology. The lack of unified resources to teach an introductory course with mathematical themes, historical content, and current cryptographic relevance required her to piece together material from various sources. She had considerable success with The Science of Secret Writing: more students requested it at registration time than could be accommodated, her own insights and teaching abilities made the course itself lively and appealing to the students enrolled, and students from a wide range of academic disciplines learned some mathematics and cryptology. The experience convinced her that there was a genuine need for an up-to-date introductory cryptology text, and this prompted her to seek National Science Foundation (NSF) funding to develop materials for such a course. A guiding principle was to introduce mathematics in the context of cryptology. This book is the result of Terri's application for that funding, of the foundation's awarding it, and of a great deal of work, teaching, and writing in the interim. Unfortunately for those who use this text, very little of it is Terri's writing. Almost coincident with the awarding of funding for the project, Terri was called to serve in an administrative capacity at Rhodes College. The demands of this post were such that it would be extraordinarily difficult for her to work on the cryptology project, and indeed its fate was, for a time, in question. In 1997, through conversations with and encouragement from Terri, I embarked on the project: teaching the second offering of Secret Writing, doing research, and writing materials based on her course notes from the first offering of Secret Writing. I became "Chief Staff Mathematician" on the project. With her continuing consultation and reviewing of early drafts, the book has evolved into its present form. This book is directed toward those whose mathematical background includes college-preparatory courses such as high school algebra and geometry. In earlier drafts, I have used it as the basis for a course for which there were no formal mathematical prerequisites at the college level. Students majoring in areas ranging from Art History to Zoology took the course. Many had not taken mathematics in four or five years. The purpose of the book is to introduce students to segments of history and current cryptol
