Alice wants to send a confidential message to Bob using the RSA encryption. To ensure that only Bob can read the message, Alice should:Group of answer choicesEncrypt the message with her own private key, allowing Bob to decrypt it with Alice's public key, ensuring authenticity.Encrypt the message with Bob's public key, ensuring that only Bob can decrypt it with his private key, ensuring confidentiality.Encrypt the message with Bob's private key, ensuring that anyone with Bob's public key can decrypt it, ensuring integrity.Encrypt the message with her own public key, allowing Bob to decrypt it with Alice's private key, ensuring non-repudiation.
