Which of the following is a true statement about the use of public key encryption in transmitting messages?ResponsesPublic key encryption enables parties to initiate secure communications through an open medium, such as the Internet, in which there might be eavesdroppers.Public key encryption enables parties to initiate secure communications through an open medium, such as the Internet, in which there might be eavesdroppers.Public key encryption is not considered a secure method of communication because a public key can be intercepted.Public key encryption is not considered a secure method of communication because a public key can be intercepted.Public key encryption only allows the encryption of documents containing text; documents containing audio and video must use a different encryption method.Public key encryption only allows the encryption of documents containing text; documents containing audio and video must use a different encryption method.Public key encryption uses a single key that should be kept secure because it is used for both encryption and decryption.

The true statement about the use of public key encryption in transmitting messages is: "Public key encryption enables parties to initiate secure communications through an open medium, such as the Internet, in which there might be eavesdroppers."

Here's why:

1. Public key encryption is a method used to initiate secure communications through an open medium, such as the Internet, even when there might be eavesdroppers. This is done by using two keys: a public key, which can be freely distributed and used by anyone to encrypt messages, and a private key, which is kept secret by the recipient and used to decrypt messages.

2. The statement that public key encryption is not considered a secure method of communication because a public key can be intercepted is false. Even if a public key is intercepted, it cannot be used to decrypt the messages. Only the private key can do that, and it is kept secret.

3. The statement that public key encryption only allows the encryption of documents containing text is also false. Public key encryption can be used to encrypt any type of data, including audio and video.

4. The statement that public key encryption uses a single key that should be kept secure because it is used for both encryption and decryption is false. This describes symmetric encryption, not public key encryption. In public key encryption, two keys are used: a public key for encryption and a private key for decryption.
