Karsten Nohl, the founder of Berlin's Security Research Labs, has announced an exploit for SIM cards using the outdated 56-bit DES algorithm for its signature verification.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

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 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 ...

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 ...

MOSCOW--(BUSINESS WIRE)--Openwall, an open source-based, professional IT and security services company, has released an updated version of “John the Ripper,” a password security auditing tool and open ...

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 ...

Tor has announced improved encryption and security for the circuit traffic by replacing the old tor1 relay encryption algorithm with a new design called Counter Galois Onion (CGO).
