Show answer & explanation
Correct answer: B
Key idea: Asymmetric encryption uses a public key and a private key.
Public key: can be shared openly for encryption or verification.
Private key: is kept secret by its owner.
Advantage: the two parties do not need to securely share the same secret key beforehand.
It is usually slower and computationally costlier than symmetric encryption, and it generally needs larger key sizes for comparable security.
Final answer: No need to securely share a secret key beforehand
