Abstract
Embodiments relate to vectorized Galois field multiplication. An aspect includes an input of first and second input operands of equal sizes into a single hardware tree, a calculation of a predicted parity as a parity of the first input operand ANDed with a parity of the second input operand, a comparison of the predicted parity with a parity generated on a final result of a Galois field multiplication of the first and second operands and a raising of an error based on a mismatch between the predicted parity and the generated parity.
