NIST has opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short "fingerprint" for use in digital signatures, message ...

Perceptual hash functions aim to imitate human perception by focusing on the types of features that drive human sight and hearing.

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

What are Merkle trees and how do they work? A binary tree that uses cryptographic hash algorithms is called a Merkle tree. A hash tree also referred to as a Merkle tree, has labeled leaf nodes ...

For Bitcoin specifically, the hashing algorithm difficulty adjusts up and down depending on how high the hash rate is. This is because creation of new Bitcoin was designed to be controlled over time.

The National Institute of Standards and Technology today announced a public competition to pick a new cryptographic hash algorithm that would become the new federal information processing standard ...
