Quasigroup Representation of Some Feistel and Generalized Feistel Ciphers

Advances in Intelligent Systems and Computing, 2013
There are several block ciphers designed by using Feistel networks or their generalization, and some of them allow to be represented by using quasigroup transformations, for suitably defined quasigroups. We are interested in those Feistel ciphers and

Revisiting Key-Alternating Feistel Ciphers for Shorter Keys and Multi-user Security [PDF]

Lecture Notes in Computer Science, 2018
Key-Alternating Feistel (KAF) ciphers, a.k.a. Feistel-2 models, refer to Feistel networks with round functions of the form $F_i(k_i\oplus x_i)$, where $k_i$ is the (secret) round-key and $F_i$ is a public random function.

Secure Quaternion Feistel Cipher for DICOM Images

IEEE Transactions on Image Processing, 2019
An improved and extended version of a quaternion-based lossless encryption technique for digital image and communication on medicine (DICOM) images is proposed. We highlight and address several security flaws present in the previous version of the algorithm originally proposed by Dzwonkowski et al. (2015).
