I'll take the (previous version of the) question as: how to implement a secure hash function $H3$ with 3 arguments, from one hash function $H$ with 1 argument, all with argument(s) in $\{0,1\}^*$. Note: For a concrete $H$ with the destination set $\mathbb Z_p^*$ thought in the question, we could use SHA3-512 followed by a suitable function; for example, ...


Assuming that the probability distributions of $\pi_{k_1}$ and $\pi_{k_2}$ are both uniform (that is, each permutation can take on any particular setting with probability $1/n!$), then no, adversary does not have enough information to learn anything about the original positions. This remains true even if we assume the adversary can perform unbounded ...
