Cellular Neural Network Encryption Scheme for Time Synchronization and CPAs Resistance in OFDM-PON
IEEE Access, 2019 In this paper, we first experimentally demonstrate a novel cellular neural network (CNN)-based physical layer encryption scheme to achieve the capability of chosen-plaintext attacks (CPAs) resistance and time synchronization simultaneously in orthogonal ...

Integral and impossible‐differential attacks on the reduced‐round Lesamnta‐LW‐BC
IET Information Security, 2022 Lesamnta‐LW‐BC is the internal block cipher of the Lesamnta‐LW lightweight hash function, specified in ISO/IEC 29192‐5:2016. It is based on the unbalanced Feistel network and Advanced Encryption Standard round function.

A General Analysis of the Security of Elastic Block Ciphers [PDF]
, 2005 We analyze the security of elastic block ciphers in general to show that an attack on an elastic version of block cipher implies a polynomial time related attack on the fixed-length version of the block cipher.

Integral Cryptanalysis of WARP based on Monomial Prediction
IACR Transactions on Symmetric Cryptology, 2022 WARP is a 128-bit block cipher published by Banik et al. at SAC 2020 as a lightweight alternative to AES. It is based on a generalized Feistel network and achieves the smallest area footprint among 128-bit block ciphers in many settings.

Design of AL-13 Block Cipher Algorithm Based On Extended Feistel Network
Journal of Physics: Conference Series, 2019 In this paper, we design a new block cipher algorithm called AL-13. The structure of AL-13 is simple. We use Extended Feistel Network Type II with input-output 128 bits and key input 256 bits.

Distinguishing attack on five-round Feistel networks
Electronics Letters, 2003 Recently it was shown (by J. Patarin) how to distinguish a general five-round Feistel network from a random permutation using (23n/2) chosen plaintexts or (27n/4) known plaintexts. The present authors report improvement of these results and a distinguisher is presented which uses roughly 2n chosen plaintexts or roughly 23n/2 known plaintexts.

Equivalence of Generalised Feistel Networks
IACR Transactions on Symmetric CryptologyThis paper focuses on equivalences between Generalised Feistel Networks (GFN) of type-II. We introduce a new definition of equivalence which captures the concept that two GFNs are identical up to re-labelling of the inputs/outputs, and give a procedure to test this equivalence relation.
