Abstract
Systems and methods for providing an S-box. The methods comprise: implementing a plurality of layers on a field programmable gate array, wherein each of the layers comprises a substitution sublayer and a mixing sublayer. The substitution sublayer comprises a plurality of μ-boxes that are each configured to perform a different randomly chosen non-linear bijective mapping from GF(2) to GF(2). The mixing sublayer is configured to (i) compute a plurality of product terms each representing a product of an element of a maximum distance separable matrix M and an output from one of the plurality of μ-boxes, and (ii) compute a plurality of column vector elements each comprising a sum of respective ones of the plurality of product terms.
