One of the first and most used hashing algorithms in blockchains is SHA-256 so the main
aim of this paper is how to increase the security level of the blockchain based on the …

In recent years, cryptologists have been delving into chaos theory to design more secure
cryptographic primitives. However, many existing chaos-based algorithms are slow due to …

Chaotic maps have various properties that mirror the security requirements of cryptographic
algorithms. As such, researchers have utilized them in the design of algorithms such as hash …

In this paper, we propose, implement, and analyze the structures of two keyed hash
functions using the Chaotic Neural Network (CNN). These structures are based on Sponge …

In this paper, we designed, implemented, and analyzed the performance, in terms of security
and speed, of two proposed keyed Chaotic Neural Network (CNN) hash functions based on …

The hash functions are the most useful primitives in cryptography. They play an important
role in data integrity, message authentication, digital signature and authenticated encryption …
