Preface
Feistel ciphers take an important part in secret key cryptography from both theoretical and practical point of view. After DES, Feistel ciphers used in the Industry had a dynamic revival. First of all, new schemes have been published, like GOST in Russia, RC-6 and SIMON in the United States. On the other hand, new needs appeared, beyond resistance against classical cryptography attacks, like resistance to physical attacks, or obfuscation. With Feistel ciphers, it is very easy to generate permutations from various round functions. This allowed to construct many proprietary algorithms (hence secret algorihtms) for specific needs and used by the Industry. This is why we considerd that is was needed to have an up to date comprehensive survey on different kinds of Feistel ciphers, including attacks and security results. From a theoretical point of view, it is from these ciphers that Luby and Rackoff proved i
