Double hashing thresholds via local weak convergence [PDF]
2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013 A lot of interest has recently arisen in the analysis of multiple-choice "cuckoo hashing" schemes. In this context, a main performance criterion is the load threshold under which the hashing scheme is able to build a valid hashtable with high probability in the limit of large systems; various techniques have successfully been used to answer this ...

Generic Attacks on Double Block Length Sponge Hashing
IACR Transactions on Symmetric CryptologyThe sponge construction is one of the main modes of operation for hash functions. Using a permutation of width b = r + c, the sponge construction with rate r and capacity c is indifferentiable up to Ω(2c/2) permutation calls.
