The Hadamard multiary quasigroup product
The Hadamard quasigroup product has recently been introduced as a natural generalization of the classical Hadamard product of matrices. It is defined as the superposition operator of three binary operations, one of them being a quasigroup operation. This

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

On isomorphisms of quasigroups
Discrete Mathematics and Applications, 2005Summary: We give a solution of the well-known problem of isomorphisms of the quasigroups each of which is principally isotopic to the same quasigroup.

Quasigroups, right quasigroups and category coverings
Algebra Universalis, 1996An interpretation of quasigroup modules as representations of the fundamental groupoid on the Cayley diagram of a quasigroup is constructed. Generalizations to right quasigroups involve the path category of the Cayley diagram.

Medially nilpotent distributive quasigroups and CH-quasigroups
Siberian Mathematical Journal, 1987The notion of medial nilpotent quasigroup is introduced. Among other facts, the following claim is proved: If (Q,.) is a distributive quasigroup, or a CH-quasigroup with \(n+2\) free generators, then (Q,.) is a medial nilpotent quasigroup of the class n (Theorem 4).

Hardware Implementation of Quasigroup Encryption for SCADA Networks
, 2014 —We present an efficient hardware implementation of a quasigroup block cipher system. Power and resource comparisons are done with AES and we show that the proposed quasigroup system provides an inexpensive alternative for SCADA networks and other low ...
