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 ...

Karsten Nohl, the founder of Berlin's Security Research Labs, has announced an exploit for SIM cards using the outdated 56-bit DES algorithm for its signature verification. The security researcher ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics. In our increasingly digital lives, ...

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 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 ...

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 ...

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 ...

Cryptographic algorithms can be roughly classified in two categories: Encryption algorithms transform an input file into an output file from which it is (quite) impossible to recover the original ...

The mission of the US National Institute of Standards and Technology, NIST, is to create technical and measurement standards to make US manufacturing and industry more competitive. In 1987, the ...

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 ...
