Question

Which of the following statements about asymmetric key cryptography is true?

A: Asymmetric key cryptography uses one shared key.
B: Asymmetric key cryptography is also called private key cryptography.
C: Asymmetric key cryptography uses two keys called public keys.
D: Asymmetric key cryptography is also called public key cryptography.

Answer 1

Asymmetric key cryptography is also called public key cryptography, and it uses two keys called public keys.

Step-by-step explanation:

The correct statement about asymmetric key cryptography is option D: Asymmetric key cryptography is also called public key cryptography.

Asymmetric key cryptography is a method of encryption that uses two different keys, one for encryption (public key) and one for decryption (private key). The public key can be freely shared with others, while the private key must be kept secret. This allows for secure communication between two parties without the need for a shared key.
