Deck-Based Wide Block Cipher Modes and an Exposition of the Blinded Keyed Hashing Model
IACR Transactions on Symmetric Cryptology, 2020 We present two tweakable wide block cipher modes from doubly-extendable cryptographic keyed (deck) functions and a keyed hash function: double-decker and docked-double-decker.

Bipartite Random Graphs and Cuckoo Hashing [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 The aim of this paper is to extend the analysis of Cuckoo Hashing of Devroye and Morin in 2003. In particular we make several asymptotic results much more precise.

Load Thresholds for Cuckoo Hashing with Double Hashing.
16th Scandinavian Symposium and Workshops on Algorithm Theory (SWAT 2018), 2018 In k-ary cuckoo hashing, each of cn objects is associated with k random buckets in a hash table of size n. An l-orientation is an assignment of objects to associated buckets such that each bucket receives at most l objects. Several works have determined load thresholds c^* = c^*(k,l) for k-ary cuckoo hashing; that is, for c < c^* an l-orientation ...

The analysis of double hashing
Journal of Computer and System Sciences, 1978 In this paper we analyze the performance of double hashing, a well-known hashing algorithm in which we probe the hash table along arithmetic progressions where the initial element and the increment of the progression are chosen randomly and independently depending only on the key \(K\) of the search.

Assessing Blockchain Consensus and Security Mechanisms against the 51% Attack
Applied Sciences, 2019 The 51% attack is a technique which intends to fork a blockchain in order to conduct double-spending. Adversaries controlling more than half of the total hashing power of a network can perform this attack.

The most efficient indifferentiable hashing to elliptic curves of j-invariant 1728
Journal of Mathematical Cryptology, 2022 This article makes an important contribution to solving the long-standing problem of whether all elliptic curves can be equipped with a hash function (indifferentiable from a random oracle) whose running time amounts to one exponentiation in the basic ...

Palm-Print Pattern Matching Based on Features Using Rabin-Karp for Person Identification
The Scientific World Journal, 2015 Palm-print based individual identification is regarded as an effectual method for identifying persons with high confidence. Palm-print with larger inner surface of hand contains many features such as principle lines, ridges, minutiae points, singular ...
