Abstract
An embodiment expands a polynomial into a plurality of products, each product in the plurality of products comprising a scaling coefficient multiplied by a sub-polynomial, each sub-polynomial comprising a sum of a plurality of addends, wherein a degree of each sub-polynomial is equal to a grouping parameter. An embodiment computes a plurality of ciphertext products, each ciphertext product equal to a ciphertext multiplied by itself a number of times, the number of times ranging from two to the grouping parameter. An embodiment computes, using the ciphertext and the plurality of ciphertext products in place of a variable of the polynomial, each of the plurality of products. An embodiment multiplies the plurality of products together.
