The block cipher E is a pseudo-random permutation (PRP) if no adversary has an advantage significantly greater than 0, given specified restrictions on q and the adversary's running time. If in Step 2 above adversaries have the option of learning f −1 ( X ) instead of f ( X ) (but still have only small advantages) then E is a strong PRP (SPRP).
