Structural cryptanalysis and storage efficiency of Kronecker-product diffusion layers for lightweight block ciphers
The results demonstrate that while insecure as a standalone primitive, this structure offers a favorable trade-off between large-state diffusion and implementation cost, making it a compelling candidate for the mixing layer in lightweight Substitution-Permutation Networks (SPNs).
