With its lively, conversational tone and practical focus, this new edition mixes applied and theoretical aspects for a solid introduction to cryptography and security, including the latest significant advancements in the field.


Balances applied and theoretical aspects of security Presents applications and protocols where cryptographic primitives are used in practice, such as SET and SSL.

Coverage of Rijndael and AES Provides a detailed explanation of AES, which has replaced Feistelbased ciphers (DES) as the standard block cipher algorithm.

Coverage of practical applications of cryptography to security protocols Connects the cryptographic tools developed earlier in the book to the building of real security tools, demonstrating to students that there is more to security and cryptography than just math.

Friendly, storylike discussion of security concepts Uses historical examples to illustrate the concepts of security and cryptanalysis by relating theory to easiertograsp events.

Modern methods such as Elliptic curves, Lattice methods, and Quantum Techniques Provides thorough coverage of topics that are becoming increasingly prominent in the field.

Major coverage of coding theory Offers a discussion of coding theory, which is often covered in todays cryptology courses.

Numerous example calculations Includes many examples, especially in purely mathematical chapters such as Ch. 3.

Public key certificate Provides an example of what an actual public key certificate looks like, rather than just describing it.

Mathematica/Maple/Matlab problems and notebooks Allow students to work with realistic sized examples in RSA and Digital Signatures, as well as classical cryptosystems and those with elliptic curves.

Practical examples and applications Give students handson experience with the largenumbered cryptography of todays security systems, and provides a discussion of security protocols.
