Which of the following statements about symmetric and asymmetric cryptography is true?
A.
Asymmetric encryption has faster performance, slower to implement, and uses only one key.
B.
Asymmetric encryption is slower than symmetric, encrypts keys, and uses a key pair.
C.
Symmetric encryption uses in-band key exchange, has faster performance, and uses a single key.
D.
Symmetric encryption has faster performance, is slower to implement, and uses a key pair.
Explanation:
Asymmetric, through its use of dual keys that are extraordinarily
long, requires more computations and longer processing times. Symmetric encryption
uses a single secret key for encryption and decryption.
