Abstract
Aspects of the present disclosure describe a method and a system to support execution of the method to perform a cryptographic operation involving identifying an N-word number, X=XN−1 . . . XX, to be squared, performing a first loop comprising M first loop iterations, wherein M is a largest integer not exceeding (N+1)/2, each of the M first loop iterations comprising a second loop that comprises a plurality of second loop iterations, wherein an iteration m of the second loop that is within an iteration j of the first loop comprises computing a product X*Xof a word Xand a word X, wherein a+b=2j+m, j≥0 and m≥0, and wherein all second loops have an equal number of second loop iterations.
