Practically Secure Feistel Ciphers
Lars Ramkilde Knudsen · DAIMI Report Series · 1994
In this paper we give necessary design principles to be used, when constructing secure Feistel ciphers. We introducee a new concept, practical security against linear and differential attacks on Feistel ciphers. We give examples of such Feistel ciphers (practically) resistant to differential attacks, linear attacks and other attacks.
