Encryption
Cryptographic transformation of plaintext into ciphertext that conceals the data’s original meaning to prevent it from being known or used (See “decryption”) [11].
- NOTE: If the transformation is reversible, the corresponding reversal process is called “decryption,” which is a transformation that restores encrypted data to its original state.
