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 ...

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 ...

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 ...

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 ...

A proprietary algorithm developed by RSA Data Security, Inc., RC2 is an alternative to DES. The algorithm expands a single message by up to 8 bytes. RC2 is a block cipher that encrypts data in blocks ...

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, ...

Before we move into the meat of this article, let’s define a couple terms related to cryptography. The syllable crypt may make you think of tombs, but it comes from a Greek word that means “hidden” or ...

The Protocol-IP-338 (EIP-338) is a scalable, high-performance, multi-stream cryptographic engine that offers XTS and GCM modes of operation for the AES algorithms on bulk data. Its flexible ... The ...
