What are the disadvantages of using a public key algorithm compared to a symmetric algorithm?

  1. A symmetric algorithm provides better access control.

  2. A symmetric algorithm is a faster process.

  3. A symmetric algorithm provides nonrepudiation of delivery.

  4. A symmetric algorithm is more difficult to implement

B Correct answer
Explanation

Public key algorithms involve complex mathematical computations, making them significantly slower than symmetric algorithms for encrypting large volumes of data. Symmetric algorithms do not offer better access control or nonrepudiation, and are generally simpler to implement.
