A stream cipher is an encryption method in which data is encrypted one byte at a time. In this method, a cryptographic key and algorithm are applied to each binary digit in a plaintext data stream to ...

Fumio Futami at Tamagawa University, Quantum ICT Research Institute, announced the world first transmission of the stream cipher by Yuen 2000 protocol (Y-00) at the bit rate of 40 Gbit/sec over 120 km ...

Immediate algorithms on quantum computers could effortlessly decipher numerous cryptosystems, requiring more ingenious resolutions for security in a digital world. Scientists at Ritsumeikan University ...

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 ...

How do we know if the electronic keys we use in our devices are really secure? While it is possible to rigorously test the strength of a cipher—a kind of digital data lock—there are rarely any ...

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, ...

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 ...

In cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Transposition ciphers keep all the original bits of ...

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 ...
