What is an important disadvantage of using a public key algorithm compared to a symmetric algorithm?
A.
A symmetric algorithm provides better access control.
B.
A symmetric algorithm is a faster process.
C.
A symmetric algorithm provides nonrepudiation of delivery.
D.
A symmetric algorithm is more diffi cult to implement.
Explanation:
B: Processing effi ciency of asymmetric cryptography is less than symmetric cryptography due to relative computational processing resources needed. Its lower performance is a disadvantage of asymmetric cryptography. Page 358.
