Véase cifrado. [ISO-7498-2:1989]
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.
