Recommended texts
-
Introduction to Cryptography with Coding Theory by Wade Trappe and Lawrence C. Washington, ISBN 0-13-186239-1 (Z 52.8 TRA). Covers most of the course (and much more) with discussion of both the mathematics and computational implementations of cryptography.
-
The Code Book by Simon Singh, ISBN 1857028899 (Z 52.8 SIN) is a good, not too mathematical, history of coding and cryptography.
-
Applied Cryptography by Bruce Schneier, ISBN 0471117099 (Z 52.8 SCH) is an amusing read.
-
Understanding cryptography: a textbook for students and practitioners by Christof Paar and Jan Pelzl. Available as an e-book from the library. This concentrates on the practical and computational applications of this course.
-
Introduction to Modern Cryptography by Jonathan Katz and Yehuda Lindell, ISBN 978-1-4665-7026-9. This book attempts to give a rigorous overview of many cryptographic ideas, and so is an excellent read if you are interested in further reading around the subject.
