Which of the following is the BEST method to ensure the security of encryption keys when transferring data containing personal information between cloud applications?

The correct answer is B. Asymmetric encryption. Asymmetric encryption (public-key cryptography) is the best choice for securely transferring encryption keys between cloud applications because it solves the key distribution problem: a sender encrypts the data (or a session key) with the recipient's public key, and only the reci

Explanation

Asymmetric encryption (public-key cryptography) is the best choice for securely transferring encryption keys between cloud applications because it solves the key distribution problem: a sender encrypts the data (or a session key) with the recipient's public key, and only the recipient's private key can decrypt it. The private key never needs to be transmitted. Symmetric encryption uses the same key for encryption and decryption, creating the challenge of how to securely share that key in the first place. Whole disk encryption protects data at rest, not in transit. Digital signatures provide integrity and non-repudiation but do not encrypt data or protect key confidentiality.
