Abstract
An electronic calculating device () arranged to convert an input number (y) represented ((y, y, . . . , y)) m a residue number system (RNS) to an output number represented in a radix representation ((e, e, . . . e)), the calculating device comprising an input interface () arranged to receive the input number (y) represented in the residue number system, and a processor circuit () configured to iteratively update an intermediate number (ŷ) represented in the residue number system, wherein iterations produce the digits (e, e, . . . e) in the radix representation with respect to the bases (b, b, . . . , b), at least one iteration comprises computing the intermediate number modulo a base (b) of the radix representation to obtain a digit (e=(ŷ)) of the radix representation, updating the intermediate number (ŷ←(ŷ−e+F)/b) by subtracting the digit from the intermediate number, adding an obfuscating number (F; F), and dividing by the base (b).
