Question

Quizplus · Accepted Answer

Asymmetric cryptography uses a public key to encrypt messages and a private key to decrypt them. Therefore, only the private key owner can read the messages. Choice A is incorrect because the private key is only used for decryption, while the public key is used for encryption. Choice B is incorrect because asymmetric cryptography does not use a shared key. Choice C is incorrect because asymmetric cryptography uses different keys for encryption and decryption, and they are not transferred using a key management system.
