Permutation-Based Hashing Beyond the Birthday Bound

IACR Transactions on Symmetric Cryptology
It is known that the sponge construction is tightly indifferentiable from a random oracle up to around 2c/2 queries, where c is the capacity. In particular, it cannot provide generic security better than half of the underlying permutation size.
