At ETH Denver, developers warned that advances in quantum computing could threaten Bitcoin’s digital signatures as the industry continues to debate how to prepare.

THE transition from paper to pixels relies on a sophisticated layer of mathematics that ensures a document remains unchanged from the moment of signing. A ...

The world of Bitcoin and cryptocurrency has long been hailed as a revolutionary financial system, offering decentralized transactions and heightened ...

ABSTRACT: A new nano-based architectural design of multiple-stream convolutional homeomorphic error-control coding will be conducted, and a corresponding hierarchical implementation of important class ...

In cryptography, **SHA-256** (Secure Hash Algorithm 256-bit) is a patented cryptographic hash function that outputs a value that is 256 bits long. It is a member of the SHA-2 family of algorithms, ...

Abstract: In this paper, Chen chaotic system with relatively high complexity is used to construct hash function. Aiming at the low efficiency of hash function constructed by high-dimensional ...

Computing practitioners encounter hash functions almost every day, although they may not necessarily be the center of attention. When you install software packages or updates, the authenticity of a ...

The article proposes a new quantum-resistant cryptographic algorithm constructed based on the OTP (One-Time Pad) cipher and a hash function. By inheriting the property of “perfect secrecy” from the ...
