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 ...

Woodcliff Lake, New Jersey — March 3, 2025 — Semiconductor intellectual property core provider CAST today announced a new IP core that implements the SNOW-V stream cipher algorithm to meet the ...

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 ...

Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers. Fast algorithms on quantum computers could easily break many widely used cryptosystems, ...

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, ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...
