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 ...

Such high-speed features of VSC come from full-scalable encryption algorithm as described as follows. VECTOR STREAM CIPHER AS FULL-SCALABLE CHAOTIC ENCRYPTION Our VSC is a kind of stream cipher. Thus, ...

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 ...

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 ...

It’s been more than 25 years since Ron Rivest invented his RC4 stream cipher, and after all that time it’s still being used widely, which is something of an achievement in the crypto world. However, ...

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 ...
