The analysis of double hashing

open access: yesJournal 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.

Generic Attacks on Double Block Length Sponge Hashing

open access: yesIACR Transactions on Symmetric Cryptology
The 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.

Double hashing thresholds via local weak convergence [PDF]

open access: yes2013 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 ...

Securing Financial Transactions with a Robust Algorithm: Preventing Double-Spending Attacks

open access: yesComputers, 2023
A zero-confirmation transaction is a transaction that has not yet been confirmed on the blockchain and is not yet part of the blockchain. The network propagates zero-confirmation transactions quickly, but they are not secured against double-spending ...

The Cost of Bitcoin Mining Has Never Really Increased

open access: yesFrontiers in Blockchain, 2020
The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from 2010 to 2020, taking into account changes in energy costs, improvements in ...
