Which term is the information scrambling algorithm?

• A. Encryption
• B. Backup
• C. Encryption Key
• D. Decryption Key

Answer: (C)

The essential idea is that scrambling information is done by encryption—the process or algorithm that turns readable text into unreadable ciphertext. The encryption key is the secret value used by that algorithm to perform the transformation; it can vary depending on whether the system is symmetric (same key for encryption and decryption) or asymmetric (different keys for encrypting and decrypting). The decryption key serves the reverse role, recovering the original data with the appropriate key. Backup is unrelated to scrambling, as it refers to making copies of data. So the term that describes the scrambling algorithm itself is encryption, while the key is a component that enables the process.
