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).

One of the applications of the Extended Euclidean Algorithm is to calculate the multiplicative inverse of a number. We know that the algorithm gives the GCD of two numbers plus numbers x and y that satisfy the equation ax + by = gcd (a,b). If gcd (a,b)=1, then y is the multiplicative inverse of b mod a. This means that b*y mod a =1. portsmouth nh boy died
