Question

Sometimes called secret key algorithms, ____________________ key algorithms use the same key to encrypt and to decrypt the data.

a) Public
b) Asymmetric
c) Symmetric
d) Hashing

Answer 1

Symmetric key algorithms use the same key for both encryption and decryption. They are also known as secret key algorithms, distinct from asymmetric key algorithms which use a key pair.

Step-by-step explanation:

Sometimes called secret key algorithms, c) symmetric key algorithms use the same key to encrypt and to decrypt the data. In contrast to asymmetric algorithms, which use a pair of keys (public and private), symmetric key algorithms deploy the same single key for both encryption and decryption processes. This key must be shared or distributed securely between parties in advance. One classic example of a symmetric key algorithm is the Advanced Encryption Standard (AES), widely used for secure data transmission.
