Cryptography, An Introduction : Third Edition

The third edition is now online. You may make copies and distribute the copies of the book as you see fit, as long as it is clearly marked as having been authored by N.P. Smart.

We give a numbering system to present versions.

The current number is 3.0.1.3 : book.ps and book.ps.gz.

Note:

As of May 19th 2016 I will no longer be updating this book with corrections for this book. Readers should instead purchase the book Cryptography Made Simple.
