Question

Which of the following statements is true of symmetric encryption?

A) It uses the same key for both encoding and decoding.
B) It is more difficult and slower than asymmetric encryption.
C) It does not require a key to encrypt or decrypt data.
D) It uses a special version called public/private key on the Internet for a secure communication.

Answer 1

Symmetric encryption uses the same key for both encoding and decoding.

Step-by-step explanation:

The correct statement about symmetric encryption is option A) It uses the same key for both encoding and decoding.

Symmetric encryption, also known as secret key encryption, uses a single key to both encrypt and decrypt data. This key is shared between the sender and the recipient.

Examples of symmetric encryption algorithms include Advanced Encryption Standard (AES) and Data Encryption Standard (DES).
