Classification: CPC G | IPC G  H

Claim 2:
3. The computer-implemented method of claim 1, wherein the computation result for a first cryptographic element c1 is a result of a polynomial multiplication c1c2 and wherein c2 is a second cryptographic element, further comprising:
storing polynomial coefficients of the second cryptographic element c2 in the multiply-accumulate unit as respective multibit values in a first column of said matrix;
in successive computation stages, progressively shifting the polynomial coefficients of element c1 relative to a set of word-lines connected to cells storing coefficients of c2 until coefficients of c1 have been supplied bitwise to word-lines in the set of word-lines; and
processing the digital signals obtained, in each of the computation stages, from the set of bit-lines connected to cells storing the coefficients of c2 and from successive bits of the coefficients of c1 to obtain the result of the polynomial multiplication c1c2.
