Abstract
Some embodiments are directed to an electronic computation device () arranged for obfuscated execution of a multiplication. The device comprises a storage () arranged for storing multiple variables used in the execution of an arithmetic operation, a variable (x: y; 2) of the multiple variables being represented as multiple multiplicative shares (X=(x, x, . . . , x); Y=(y, y, . . . , y);), said multiplicative shares being represented in the storage as multiple additive shares (x=(x,x, . . . , x); Yi=(y,0,y, . . . , y);).
