It is known that a super-pseudorandom permutation on 2n bits can be obtained from a random function f on n bits and two bi-symmetric and AXU hash functions h_1 and h_2 on n bits. It has a Feistel type structure which is usually denoted by φ(h_1, f, f, h_2). Bi-symmetric and AXU hash functions h_1, h_2 are much weaker primitives than a random function f and they can be computed much faster than random functions. This paper shows that we can further weaken the condition on h_1.
