Feistel networks are one of the easiest ways to build pseudorandom permutations. Thanks to this property, many secret key algorithms (symmetric ciphers) have been designed as Feistel networks, and it is possible to design many others. The most famous of them is probably the Data Encryption Standard algorithm, a former U.S. National Institute of Standards and Technology standard block cipher, originally released in 1977.This book provides a comprehensive survey of different kinds of Feistel ciphers, including their definitions and mathematical/computational properties.Topics and features:Description of the best-known attacks against the Data Encryption Standard algorithm, including linear cryptanalysis, differential cryptanalysis, and Davies’ attackGeneric attacks against balanced, unbalanced, and generalized Feistel networksUp-to-date security analysis of balanced Feistel networksQuantum cryptanalysis of Feistel networksThe results consolidated in this volume provide an overview of this important cipher design to researchers and practitioners willing to understand the design and security analysis of Feistel ciphers.

This book provides a survey on different kinds of Feistel ciphers, with their definitions and mathematical/computational properties. Feistel ciphers are widely used in cryptography in order to obtain pseudorandom permutations and secret-key block ciphers. In Part 1, we describe Feistel ciphers and their variants. We also give a brief story of these ciphers and basic security results. In Part 2, we describe generic attacks on Feistel ciphers. In Part 3, we give results on DES and specific Feistel ciphers. Part 4 is devoted to improved security results. We also give results on indifferentiability and indistinguishability.
