This text illustrates algorithms and cryptosystems using examples and the open-source computer algebra system of Sage. It enables students to run their own programs and develop a deep and solid understanding of the mechanics of cryptography. The author, a noted educator in the field, covers the methods, algorithms, and applications of modern cry

This bestseller explores the nature and use of digital images and shows how they can be obtained, stored, and displayed. Along with MATLAB®, this second edition now includes GNU Octave and Python.

This bestseller explores the nature and use of digital images and shows how they can be obtained, stored, and displayed. Along with MATLAB®, this second edition now includes GNU Octave and Python. Programs are written as modular as possible, allowing for greater flexibility, code reuse, and conciseness. This edition also contains new images, redrawn diagrams, and new discussions of edge-preserving blurring filters, ISODATA thresholding, Radon transform, corner detection, retinex algorithm, LZW compression, and other topics.

Presenting both mathematical and security perspectives, this text reviews basic theory and discusses cryptographic protocols and systems. With an emphasis on experimentation and exploration, the text offers a wealth of practical examples and numerous exercises using the open source software Sage. An accompanying CD-ROM includes the necessary codes. The author covers private and public key cryptosystems, knapsack cryptosystems, digital signatures, random number generators, elliptic curves, block ciphers, hash functions, the DES and AES, finite fields, and message authentication codes.
