Another name for asymmetric-key cryptography is:

• A. Public-key cryptography
• B. Symmetric-key cryptography
• C. Hash-based cryptography
• D. Quantum cryptography

Answer: (A)

The key idea is that asymmetric cryptography uses two different keys with distinct roles: one key is made public so anyone can use it, and the other key is kept private for decryption or signing. Because the public key is shared openly, this approach is commonly called public-key cryptography. It contrasts with symmetric methods, where the same secret key is used for both encryption and decryption. Other terms like hash-based or quantum cryptography refer to different ideas and don’t describe the two-key setup that defines the asymmetric approach.
