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

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.
