SMASH - a cryptographic hash function

, 2005
. 1This paper presents a new hash function design, which is different from the popular designs of the MD4-family. Seen in the light of recent attacks on MD4, MD5, SHA-0, SHA-1, and on RIPEMD, there is a need to consider other hash function design ...

RainHash2.0: Hardware- and Arithmetization-friendly Hash Function

Transactions on Cryptographic Hardware and Embedded Systems
Zero-knowledge (ZK) proof systems have developed rapidly in recent years, with hash functions as one of their central building blocks. Since these often dominate the prover cost, circuit-friendly hash function design has become an active research area ...

Verification of Implementations of Cryptographic Hash Functions

IEEE Access, 2017
Cryptographic hash functions have become the basis of modern network computing for identity authorization and secure computing; protocol consistency of cryptographic hash functions is one of the most important properties that affect the security and ...

The Hash Function Fugue [PDF]

, 2014
We describe Fugue, a hash function supporting inputs of length upto 2^{64}-1 bits and hash outputs of length upto 512 bits. Notably, Fugue is not based on a compression function.

Adaptive Hashing

CoRR
Hash tables are ubiquitous, and the choice of hash function, which maps a key to a bucket, is key for their performance. We argue that the predominant approach of fixing the hash function for the lifetime of the hash table is suboptimal and propose adapting it to the current set of keys.

Spatiotemporal chaotic one-way Hash function construction based on coupled tent maps

Tongxin xuebao, 2007
A novel coupled tent maps-based spatiotemporal chaotic cryptographic Hash function was proposed.Compared with the discrete tent map,the coupled discrete tent spatiotemporal chaotic maps have longer computer-realization-period,nearly uniform distribution ...

CRUSH: A New Cryptographic Hash Function using Iterated Halving Technique

, 2004
. Most of the currently accepted designs for cryptographic hash functions are in the style of a block cipher in feed-forward mode. With increasing interest in all forms of cryptanalysis, this limited choice might become a single point of failure in ...

New hash function designs [PDF]

, 2008
We suggest new hash function design principles. The basic idea is that the hash value may be a combination of XOR\u27s and modular additions of values independently produced from different parts of the message.

Cryptanalysis of The Hwang-Shi Proxy Signature Scheme

, 2012
[[abstract]]Recently, Hwang and Shi proposed an efficient proxy signature scheme without using one-way hash functions. In their scheme, an original signer needn't send a proxy certificate to a proxy signer through secure channels.
