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 ...

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 ...

Recent advancements in cryptographic research underpin the evolution of secure digital communication systems. Cryptographic algorithms form the backbone of information security, defending data ...

In the last section we discussed the potential for optimizing algorithms, which can be done, but sometimes may not result in the type of performance required. As was mentioned, you can always move the ...

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 ...

A view of NIST headquarters in Gaithersburg, Md. (Photo credit: NIST) The National Institute of Standards and Technology announced an algorithm that could serve as a second line of defense to ensure ...

When quantum computers become powerful enough, they could theoretically crack the encryption algorithms that keep us safe. The race is on to find new ones. Tech Review Explains: Let our writers ...

Threats to computer and network security increase with each passing day and come from a growing number of sources. No computer or network is immune from attack. A recent concern is the susceptibility ...
