When quantum computers become commonplace, current cryptographic systems will become obsolete. Scientists are racing to get ahead of the problem and keep our data secure. When you purchase through ...

Cryptographic hash functions secure data by providing a unique fixed-length output for each input. These functions are essential in blockchain for data integrity and secure transactions. Understanding ...

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 ...

Cryptography, a cornerstone of modern information security, encompasses a vast array of techniques and tools designed to protect sensitive data from unauthorized access and tampering. Within this ...

Abstract: Blockchain is a decentralized system mechanism on each node. There are many aspects required to build a good blockchain system. One of the important aspects is a hash function in ...

When developing programs or websites, it is very convenient to use relational databases, which contain powerful and convenient tools that allow to work with data very flexibly and get the necessary ...

Abstract: This paper proposes a keyed hash function using absolute-value chaotic map. The proposed absolute-value chaotic map is simple with a single tuning parameter, and offers robust chaos over ...
