A) Encrypted messages cannot be deciphered without the decoding key.
B) Encryption is used for data enhancement rather than data protection.

E) Encryption implementation is an expensive process and needs an authentication from a relevant authority.

Question

Quizplus · Accepted Answer

The statement "Encrypted messages cannot be deciphered without the decoding key" correctly describes the function of encryption. Encryption is primarily used for data protection and is typically performed before the messages enter the network, contrary to option C. Encryption may or may not enhance data, so option B is incorrect. Option D is also incorrect as the encryption approach may vary depending on the data transmission method. Lastly, while encryption implementation and authentication may be costly, option E is not a valid observation about encryption as a whole.
