Encryption

Cryptographic transformation of data (called “plaintext”) into a form (called “ciphertext”) that conceals the data’s original meaning to prevent it from being known or used. If the transformation is reversible, the corresponding reversal process is called “decryption,” which is a transformation that restores encrypted data to its original state.

See  NIST SP 800-82 Rev. 2 under Encryption for more information.

The translation of data into a form that is unintelligible without a deciphering mechanism.

See NIST SP 800-47 under Encryption for more information.

Any procedure used in cryptography to convert plain text into ciphertext to prevent anyone but the intended recipient from reading that data.

See NIST SP 800-101 Rev. 1 and NIST SP 800-72 under Encryption for more information.

The process of a confidentiality mode that transforms usable data into an unreadable form.

See NIST SP 800-38A under Encryption (Enciphering) for more information.
