The first step is to obtain n = p 2 q, which we can do by computing: n = gcd ( m 1 2 − c 1, m 2 2 − c 2) by using the oracle to obtain c i from integers m i. Note: there may by other factors, and we actually compute k n for some k ∈ Z. We can ensure k = 1 by computing many m i, c i and taking the gcd many times. WebPow-Pow.
