The course is for the most part, especially part II, based on the material in
"Cryptology, Classical and Modern" by Richard Klima and Neil Sigmon.

• CCaM: Cryptology: Classical and Modern, Second Edition

The course was in earlier years based on the book "The Mathematics of Secrets" by Joshua Holden.
The paperback version has taken care of some of the errata in the hardcover edition,
so the paperback version is recommended.
