Abstract
Designing new cryptosystems and their cryptanalysis
is the basic cycle of advancement in the field of cryptography. In
this paper we introduce a block cipher based on the quasigroup
transformations, which are defined by the matrix presentation of
the quasigroup operations. This type of quasigroup presentation
is suitable for constructing a block cipher since it doesn’t require
too much memory space to store all the necessary data, so it can
be used even for lightweight cryptographic purposes.
For now, we are considering only the quasigroups of order 4.
Constructions with quasigroups of higer order and examination
of the strengths and weaknesses of this design will be considered
in next papers.
