data encryption

From The Columbia Encyclopedia
the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign governments. It is also now used increasingly by the financial industry to protect money transfers, by merchants to protect credit-card information in electronic commerce, and by corporations to secure sensitive communications of proprietary information. All modern cryptography is based on the use of algorithms to scramble (encrypt) the original message, called plaintext , into unintelligible babble, called ciphertext. The operation of the algorithm requires the use of a key. Until 1976 the algorithms were symmetric, that is, the key used to encrypt the plaintext was the same as the key used to decrypt the ciphertext. In 1977 the asymmetric or public key algorithm was introduced by the American mathematicians W. Diffie and M. E. Hellman. …

Full text Article Data Encryption Standard (DES)

From BCS Glossary of Computing and ICT
including: Advanced Encryption Standard (AES) is a standard method of encrypting data, developed by the US Government. The method specifies how a key (see encryption , page 163) is used to encode the message in a standard way. It was believed that the method was complex enough for the encrypted data…

From The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide
In computing, widely used US government standard for encryption, first adopted in 1977. DES was developed by IBM and adopted as a government standard by the National Security Agency. It is a private-key system, so that the sender and recipient encrypt and decrypt the message using the same key. This…
