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 ...

Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

Cryptographer Horst Feistel ’37 spearheaded the work leading to encryption standards used during the 20th century. On March 17, 1975, the National Bureau of Standards (NBS) published its proposed Data ...

Advanced Encryption Standard (AES) is a widely adopted and symmetric encryption algorithm standard used while securing data. It is a cryptographic standard, which was established by the US National ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

In July, the National Institute of Standards and Technologies selected four cryptography algorithms as national standards for public key security in order to prepare for an era of quantum computers, ...

The National Institute of Standards and Technology announced the first series of quantum-resistant computer algorithms, a major development to secure digital information in a post-quantum world.

At the Crypto 2004 conference in Santa Barbara, Calif., this month, researchers announced several weaknesses in common hash functions. These results, while mathematically significant, aren’t cause for ...
