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…

Construction of all MDS and involutory MDS matrices
Yogesh Kumar, P. R. Mishra, Susanta Samanta +2
In this paper, we propose two algorithms for a hybrid construction of all MDS and involutory MDS matrices over a finite field , respectively. The prop…
