"This wonderfully documented text explores the mechanics and methods of digital security and the steps necessary to ensure privacy. ... For the professional who is mathematically literate, the book is a must-read. The reference sections that follow each chapter rival that of any PhD thesis ever written. It is magnificent in its scholarship." (James Van Speybroeck, Computing Reviews, October, 2015)
