  In this paper, we propose the use of Ramanujan class of polynomials for the
construction of prime order elliptic curves using the CM-method. We compare
(theoretically and experimentally) the efficiency of using this new class
against the use of the Weber, $M_{D,l}(x)$ and $M_{D,p_1,p_2}(x)$ polynomials
and show that they clearly outweigh all of them in the generation of prime
order elliptic curves.
