Which of the following statements regarding symmetric key cryptography is false?

A.
It does not provide non-repudiation

B.
Functionality is faster than asymmetric algorithms

C.
Key management is a strength

D.
The same key is used for encryption and decryption

Explanation:
Symmetric key cryptography is faster than asymmetric algorithms. It can
only provide confidentiality and system authentication. It cannot provide
non-repudiation. One downfall is that as the number of users grow, so does the
number of keys that must be managed.
