Quizplus · Accepted Answer

The definition given matches the process of Diffie-Hellman key exchange, which involves agreeing upon a large prime number and related integer to create a shared secret key.

Answer: H
 A private key is a secret key that is kept by the owner of the key pair in asymmetric encryption. It is used to decrypt messages encrypted with the corresponding public key.

Answer: I
 A public key is a key in the public domain that can be used to encrypt messages. It is paired with a private key for decryption in asymmetric encryption.

Note: The other terms are also important in the field of cryptography, but they do not match the given definition.
