B) symmetric, public
C) Public and symmetric keys of about the same length have about equal strength.
D) None of the above

Question

Quizplus · Accepted Answer

Public keys need to be longer than symmetric keys to achieve a comparable level of security due to the differences in the underlying cryptographic algorithms. Public key algorithms (used in asymmetric cryptography) are generally less efficient and require longer key lengths to provide the same level of security as symmetric key algorithms.
