Schroeder, Manfred. 1997, 3rd edition. 420 pages.
Categories: Mathematics, Top Picks
Number Theory in Science and Communication is now in its third edition (97), and has kept up with advances since its original publication in 1984. While not primarily a cryptography book, it is a great primer for anyone who wants to understand the mathematics behind crypto (such as residues, Galois fields, primitive roots, indexes, the Chinese Remainder Theorem, etc).
