"It is by far the most suitable text for undergraduate and graduate courses on the subject in mathematics and computer science departments. Besides having breadth and scope in the choice of topics, many of them are dealt with in much more depth than what can be found elsewhere at this level . . . If you really want to learn some cryptography this is probably the best available text."
– Peter Shiu, Department of Mathematical Sciences, Loughborough University, in The Mathematical Gazette, March 2007
". . . the book is very well suited for a course in crypotography."
