“…The other function is MixFunc that used for bit permutation to provide diffusion via multiplication with constant matrix A given in (1). This matrix is MDS (Maximum Distance Separable) matrix that ensures perfect diffusion and maximum branch number [31]. Multiplication with matrix elements is in GF (2 4 ) using the irreducible polynomial x 4 +x+1.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
