Cuckoo Hashing

open access: yesBRICS Report Series, 2001
We present a simple and efficient dictionary with worst case constant lookup time, equaling the theoretical performance of the classic dynamic perfect hashing scheme of Dietzfelbinger et al. (<em>Dynamic perfect hashing: Upper and lower bounds. SIAM J. Comput., 23(4):738-761, 1994</em>).

HASHING ALGORITHM BASED ON TWO-DIMENSIONAL CHAOTIC MAPPINGS

open access: yesСистемный анализ и прикладная информатика, 2017
A new hashing algorithm based on dynamic chaos is proposed. Owing to the use of chaotic mappings, this algorithm is irreversible and a search for two messages with identical hash-values becomes computationally difficult.
