An encryption method that works with continuous streams of input rather than fixed blocks. Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an ...

Quantum noise stream ciphers utilise the inherent randomness of quantum noise in optical systems to secure data transmission at the physical layer. By embedding cryptographic keys into fluctuations ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

Cryptography is something of a cryptic field, if you’ll forgive the pun. While one researcher erects the walls of a new technique, another tries to smash it to pieces. Seemingly counterintuitive, near ...

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional ...

The National Security Agency (NSA) is offering two families of encryption algorithms, known as block ciphers, intended to provide a level of security for such processes as authentication or ...
