Which statement is true of symmetric encryption?
A)It uses two different keys to encrypt and decrypt a message.
B)It requires more processing power than asymmetric encryption.
C)It is difficult to share a key over the Internet in symmetric encryption.
D)It is impossible to create digital signatures using symmetric encryption.

Question

Quizplus · Accepted Answer

DC) Sharing a key securely over the Internet is a challenge in symmetric encryption because the same key used for encryption is also used for decryption. This means the key must be transmitted or shared in a secure manner to avoid interception.D) Digital signatures typically require asymmetric encryption, where a private key is used for signing, and a public key is used for verification. Symmetric encryption, using the same key for encryption and decryption, does not facilitate the creation of digital signatures in the same way.
