The design of cryptographic hash functions is crucial for ensuring the security of digital information. In this context, cellular automata (CAs) have emerged as a promising tool due to their inherent ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

With the wide application of blockchain comes the challenge of cross-chain interaction. For example, the isolation between the information stored in different blockchains can result in the ”isolated ...

Download this article in PDF format. On the surface, this sounds ridiculous: A lobby fish tank gets attacked by hackers. Why would anyone want to break into a fish tank (Fig. 1)? But in this case, the ...

Classical public-key cryptography derives its security from integer factorisation. Diagram by Venus Kolhi. Quantum computers bring exponential computing power, ultrafast calculations, advanced ...
