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 ...

Friday February 24, 2017 Reuters The algorithm, known as Secure Hash Algorithm 1 or SHA-1, is currently used to verify the integrity of digital files and signatures.

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

Such hash algorithms are ultimately one of the key security technologies for federal and public systems. The competition is NIST’s response to recent advances in the analysis of hash algorithms.

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

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.

Security experts vying to have their technology selected as the next cryptographic-hash algorithm standard for the U.S. government need to submit their entries this week. Then they will have a ...

Hash attack economics Starting with the basics, Bitcoin is encrypted by transactions using what's called a Secure Hashing Algorithm 256 (shortened to SHA-256).
