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 ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

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 ...
