Classification: CPC G | IPC G  H

Claim 15:
16. The computer system of claim 14, 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:
program instructions to store polynomial coefficients of the second cryptographic element c2 in the multiply-accumulate unit as respective multibit values in a first column of said matrix;
program instructions to, in successive computation stages, progressively shift 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
program instructions to process 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.
