What is the PRIMARY advantage of secret key encryption systems as compared with public key
systems?

A.
Faster speed encryption

B.
Longer key lengths

C.
Easier key management

D.
Can be implemented in software

Explanation:
“The major strength of symmetric key cryptography is the great speed at which it can operate. By
the nature of the mathematics involved, symmetric key cryptography also naturally lends itself to
hardware implementations, creating the opportunity for even higher-speed operations.” Pg. 309
