We prove that a balanced 8-round Feistel network is indifferentiable from a random permutation. This result comes on the heels of (and is part of the same body of work as) a 10-round indifferentiability result for Feistel network recently announced by the same team of authors [10]. The current 8-round simulator achieves similar security, query complexity and runtime as the 10-round simulator and is not significantly more involved. The security of our simulator is also slightly better than the… CONTINUE READING
