Innovative Cryptography (Programming Series)

Innovative Cryptography, Second Edition provides a cutting-edge evaluation and review of current findings in the area of cryptography and explores how to implement these new techniques efficiently. It covers current cryptographic problems and suggests practical solutions. The book also discusses the role of symmetric ciphers and symmetric block ciphers, and details the need for fast symmetric ciphers for hardware (DES), software (RC5, Blowfish), and universal (AES, RC6, Twofish, IDEA, GOST) implementations. In addition, the book covers the issues surrounding the development and design of software-oriented ciphers, including ciphers based on the algorithm formed depending on the secret key. Some specific issues related to the cryptographic strength of ciphers with the flexible algorithm of data transformation are considered, and a combinational probabilistic model is suggested for obtaining minimal evaluations of the software ciphers being considered. A highly promising new command suggested to be used in universal processors is also discussed. This command executes controlled bit permutation, and is expected to sharply increase the performance of cryptographic algorithms including bit permutations of arbitrary type. Innovative Cryptography, Second Edition is written for anyone involved in the development of cryptopgraphic tools, including engineers, researches, programmers, and IT security professionals. Innovative Cryptography, Second Edition covers the range of problems and mathematical basics of symmetric and asymmetric cryptography, including the systems of public key distribution and digital signatures. New advances in the development of the practical approaches to synthesis of block ciphers based on controlled transforms are also explored. The book provides classification and description of mathematical properties of new cryptographic primitives. It presents crypto schemes oriented toward effective use of data-dependent operations, a range of new fast block ciphers, and evaluates their resistance to crypt analysis. Materials for self-study and practical problems for organizing the course in the field of cryptography and information security are also provided. The companion CD-ROM includes all of the figures and source code from the book.
