Which of the following is the best means of transferring information when parties do not have a shared secret and large quantities of sensitive information must be passed?

Which of the following is the best means of transferring information when parties do not have a shared secret and large quantities of sensitive information must be passed?

A.
Use of public key encryption to secure a secret key, and message encryption using the secret key

B.
Use of the recipient�s public key for encryption, and decryption based on the recipient�s private key

C.
Use of software encryption assisted by a hardware encryption accelerator

D.
Use of elliptic curve encryption

Explanation:
Where parties do not have a shared secret and large quantities of
sensitive information must be passed, the most efficient means of transferring
information is to use a hybrid encryption technique. Hybrid encryption uses both
secret key and public key encryption.
