Abstract
An apparatus having a first circuit and a second circuit is disclosed. The first circuit may be configured to (i) generate second Galois Field elements by performing a first Galois Field inversion on first Galois Field elements, the first Galois Field inversion being different from a second Galois Field inversion defined by an Advanced Encryption Standard and (ii) generate third Galois Field elements by multiplying the second Galois Field elements by an inverse of a predetermined matrix. The second circuit may be configured to (i) generate fourth Galois Field elements by processing the third Galois Field elements in a current encryption round while in a non-skip mode, (ii) generate fifth Galois Field elements by multiplying the fourth Galois Field elements by the predetermined matrix and (iii) present the fifth Galois Field elements as updated versions of the first Galois Field elements in advance of a next encryption round.
