Abstract
A method for conducting an operation including (a) lifting coefficients of a data structure from a representation modulo q to a representation modulo q', wherein the data structure comprises values which are reduced modulo q, wherein q and are integers; (b) randomizing the coefficients in modulo q′, wherein for each coefficient a random value is multiplied with the value of q and the result of this multiplication is added to the coefficient; (c) conducting an operation on the lifted and randomized coefficients; and (d) reducing the lifted and randomized coefficients by conducting an operation modulo q.
