WebJan 20, 2015 · Finding the multiplicative inverse is in fact computationally feasible. The prime numbers p and q are not public (although n = pq is). An attacker cannot therefore know φ (n), which is required to derive d from e. The strength of the algorithm rests on the difficulty of factoring n (i.e. of finding p and q, and thence φ (n) and thence d).
