An attack on a fundamental proof technique reveals a glaring security issue for blockchains and other digital encryption ...

What Is a Hash? Understanding the Role of Hash Functions in Cryptography A hash is a mathematical function that transforms ...

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 increasing hashing ...

Hash algorithms are important components in many cryptographic applications and security protocol suites. In this paper, a unified architecture for MD5 and RIPEMD-160 hash algorithms is developed.
