Claim 7:
8. The method of claim 7, wherein producing four preliminary 8-bit results (K) by scalar multiplying each of the four 8-bit sub-results by the respective one bit of the 4-bit first output signal (Y) comprises performing a calculation according to:

R=K0·U⊕K1·U⊕K2·U·K3·U,, wherein:
Ki=Yi*Li,
i=0 . . . 3,
each Yi is a 1-bit value,
each Li is an 8-bit value, that satisfies Li=Mi*U,
each Mi is an 8×8 matrix representing 8 linear equations, and
⊕ represents an exclusive OR, XOR, operation.
