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 ...

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 ...

The National Institute of Standards and Technology (NIST) is proposing that the Data Encryption Standard (DES), a popular encryption algorithm, lose its certification for use in software products sold ...

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 ...

Karsten Nohl, the founder of Berlin's Security Research Labs, has announced an exploit for SIM cards using the outdated 56-bit DES algorithm for its signature verification.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

Cryptography is the fundamental technology used to protect information in today’s information economy. Not coincidently, it is also responsible for the commercialization of the Internet. Netscape was ...

Researchers atMIT and theUniversity of Innsbruck last week announced that they had designed and constructed the world’s first scalable quantum computer, a development that could make existing ...

The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has selected four quantum-resistant cryptographic algorithms for general encryption and digital signatures. NIST ...
