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 ...

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 ...

The new Ascon lightweight IP core offers a smaller alternative for devices with limited resources. April 27, 2023-- Xiphera releases XIP2201B, an IP core which supports the Ascon lightweight ...

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, ...

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 ...
