A New Algorithm for Computing Branch Number of Non-Singular Matrices over Finite Fields
P. R. Mishra, Yogesh Kumar, Susanta Samanta +1
The notion of branch numbers of a linear transformation is crucial for both linear and differential cryptanalysis. The number of non-zero elements in a state difference or linear m…

A Systematic Construction Approach for All Involutory MDS Matrices
Yogesh Kumar, P. R. Mishra, Susanta Samanta +1
Maximum distance separable (MDS) matrices play a crucial role not only in coding theory but also in the design of block ciphers and hash functions. Of particular interest are invol…
