I am using PBKF2 to derive a encryption key from a password. suppose entropy of my password is y and my PBKF2 function has x number of iterations. So how to calculate the entropy of finale key derived from the PBKF2 function.

According to the paper “Stronger Key Derivation Via Sequential Memory-Hard Functions”…
$$2^k = x$$
the entropy of the derived key (DK) key will be
