Permutation-Based Hash Chains with Application to Password Hashing
IACR Transactions on Symmetric CryptologyHash chain based password systems are a useful way to guarantee authentication with one-time passwords. The core idea dates back to Lamport, and is specified in RFC 1760 as S/Key. At CCS 2017, Kogan et al.

Permutation-Based Hashing Beyond the Birthday Bound
IACR Transactions on Symmetric CryptologyIt 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.
