Lightweight Diffusion Layer: Importance of Toeplitz Matrices
Toeplitz matrix MDS matrix XOR count
2016/12/10
MDS matrices are used as building blocks of diffusion layers in block
ciphers, and XOR count is a metric that estimates the hardware implementation cost.
In this paper we report the minimum value of...

The Maximum Distance Separable (MDS) mapping, used in cryptography deploys complex Galois field multiplications, which consume lots of area in hardware, making it a costly primitive for lightweight cr...
