Which of the following is the best choice for encrypting large amounts of data?
a. Asymmetric encryption
b. Symmetric encryption
c. Elliptical curve encryption
d. RSA encryption
Answer: B
Public key encryption is not usually used to encrypt large amounts of data, but it is does provide an effective and efficient means of sending a secret key from which to do symmetric encryption thereafter, which provides the best method for efficiently encrypting large amounts of data. Therefore, answers A, C, and D are incorrect.
