Which of the following would be the fastest.
A . EC
B. DH
C. RSA
D. AES

Answer: D

Explanation:

AES

https://en.wikipedia.org/wiki/Symmetric-key_algorithm AES – symmetric cipher. Symmetric keys use the same key for both encryption and decryption. Both the sender and receiver of the data must know and share the secret key. For standard encrypt/decrypt functions, symmetric algorithms generally perform much faster than their asymmetrical counterparts. This is due to the fact that asymmetric cryptography is massively inefficient. Symmetric cryptography is designed precisely for the efficient processing of large volumes of data. In other words, symmetric encryption is generally used for speed and performance, e.g. when there’s a large amount of data that needs to be encrypted/protected.
