Analyzing Linear Layers in Related-Differential Cryptanalysis
Yogesh Kumar, Akshay Ankush Yadav, Susanta Samanta
In AES-like ciphers, diffusion layers are commonly instantiated using MDS matrices, since their optimal branch number yields strong diffusion guarantees and underpins classical res…

New Insights into Involutory and Orthogonal MDS Matrices
Yogesh Kumar, Susanta Samanta, Atul Gaur
MDS matrices play a critical role in the design of diffusion layers for block ciphers and hash functions due to their optimal branch number. Involutory and orthogonal MDS matrices…
