1. (I)
Cryptographic transformation of data (called "plain text") into a
different form (called "cipher text") that conceals the data's original
meaning and prevents the original form from being used. The corresponding
reverse process is "decryption", a transformation that restores
encrypted data to its original form. (See: cryptography.)
2. (O) "The
cryptographic transformation of data to produce ciphertext." [ISO-7498-2]
Usage: For this
concept, IDOCs SHOULD use the verb "to encrypt" (and related
variations: encryption, decrypt, and decryption). However, because of cultural
biases involving human burial, some international documents (particularly ISO
and CCITT standards) avoid "to encrypt" and instead use the verb
"to encipher" (and related variations: encipherment, decipher,
decipherment).
[RFC4949:2007]
The process of
changing plaintext into ciphertext using a cryptographic algorithm and key. [NIST-SP800-57:2007]
(reversible) transformation of data by a cryptographic algorithm to produce ciphertext, i.e., to hide the information content of the data [ISO/IEC ISO-9797-1]. [ISO-18033-1:2005]
Encryption is a
cryptographic operation that is used to provide confidentiality for sensitive
information; decryption is the inverse operation.
Encrypted data is
inaccessible until decrypted, and the ability to decrypt can be limited only to
authorized receivers of the data.
Encryption is
used to protect data confidentiality; with additional features, it can also
protect data integrity (through validating that the encrypted data has not been
altered). Encryption can be used to protect data at rest and data in motion.
