Bounds for the number of rounds with impossible differences in generalized Feistel schemes
M. A. Pudovkina, A. V. Toktarev National Research Nuclear University MEPhI (Moscow Engineering Physics Institute), Moscow, Russia
Abstract:
The class of ciphers described by a generalized Feistel scheme is considered. Some upper and lower bounds for the maximum number of rounds with impossible differences are provided. They do not depend on the type of Feistel scheme and on the number of nonlinear functions or blocks in the register.
Keywords:
block cipher, generalized Feistel scheme, impossible differential, differential probability.
