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 ...

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 ...

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 ...

Introduction to ciphers and substitution. Alice and Bob and Carl and Julius: terminology and Caesar Cipher ; The key to the matter: generalizing the Caesar Cipher ; Multiplicative ciphers ; Affine ...

Stream ciphers are commonly used for wireless communications. For example, A5, the algorithm used to encrypt GSM communications, is a stream cipher. The RC4 cipher and the one-time pad (OTP) are also ...

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 ...

Secure cloud data processing has become a critical issue in recent times and while general network security techniques such as Virtual Private Networks could be used for securing the end-to-end ...
