WebJan 6, 2024 · In the special case when $n = p$ is prime, $\phi(p) = p-1$. The totient function obeys a few interesting identities which will be of use to us \[\phi(mn) = \phi(m) \phi(n) \cdot \frac{d}{\phi(d)}, \qquad d = \gcd(m,n).\] In the special case when $\gcd(m,n) = 1$, this simplifies to \[\phi(mn) = \phi(m) \phi(n).\] WebOne approach to obtaining prime numbers in instantiations of these cryptographic primitives is to produce such numbers as they are needed on whatever device requires them. This is accomplished by sampling random integers and checking for primality. This process can be computationally intensive to the point of being prohibitively so.
