چكيده لاتين :
Diffusion layers are an important part of most
symmetric ciphers and MDS matrices can be used to construct
perfect diffusion layers. However, there are few techniques for
constructing these matrices with low implementation cost in
software/hardware. Conventional MDS matrices are constructed
on finite fields and MDS matrices over commutative rings acting
on modules have been characterized by Dong Dong et. al. in 1998.
In this paper, we consider MDS matrices over commutative rings
acting on corresponding modules and using the minors of such
matrices, we construct new MDS diffusion layers.
