The analysis of double hashing

Journal of Computer and System Sciences, 1978
AbstractIn 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.

Frequent Itemset Generation using Double Hashing Technique

Procedia Engineering, 2012
AbstractIn data mining, frequent itemsets plays an important role which is used to identify the correlations among the fields of database.In this paper, we propose a new association rule mining algorithm called Double Hashing Based Frequent Itemsets, (DHBFI) in which hashing technology is used to store the database in vertical data format.

The Cost of Bitcoin Mining Has Never Really Increased [PDF]

Frontiers 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 ...

Improved Quantum Rebound Attacks on Double Block Length Hashing with Round-Reduced AES-256 and ARIA-256

IACR Transactions on Symmetric Cryptology
At EUROCRYPT 2020, Hosoyamada and Sasaki proposed the first dedicated quantum collision attacks on hash functions. Their proposal presented a quantum adaptation of the rebound attack and revealed that differential trails, which have too low probability ...

Quantum Collision Resistance of Double-Block-Length Hashing

IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences
SUMMARY In 2005, Nandi introduced a class of double-block-length compression functions h π ( x ) : = ( h ( x ) , h ( π ( x ))) , where h is a random oraclewithan n -bitoutputand π isanon-cryptographicpublicpermutation.

Some Attacks Against a Double Length Hash Proposal [PDF]

, 2005
At FSE 2005, Nandi et al proposed a method to turn an n-bit compression function into a 2n-bit compression function. In the black-box model, the security of this double length hash proposal against collision attacks is proven, if no more than Ω(22n/3) oracle queries to the underlying n-bit function are made.
