Given $y \equiv g^x \pmod p$ for some prime $p$, we want to find $x = \log_g y$. We set $g$ to be a generator of the group $\mathbb{Z}_p$ or $\mathbb{Z}_p^*$, since if $g$ is the generator, a solution always exists.

A **one-way function** is a function that is easy to compute, but hard to compute the pre-image of any output. Here are some common examples.
