Solution

The correct option is C Cryptography

Cryptography is the art of transforming message to make them secure and immune to attack.

Modern cryptography uses sophisticated mathematical equations (algorithms) and secret keys to encrypt and decrypt data. Today, cryptography is used to provide secrecy and integrity to our data, and both authentication and anonymity to our communications.

Symmetric cryptography(secret key encryption) is an encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message. ... Examples of methods that use symmetric encryption include: Advanced Encryption Standard (AES)

Cryptography is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. Cryptography is closely related to the disciplines of cryptology and cryptanalysis.
