CompTIA Security+ Question C-59

Which of the following would Matt, a security administrator, use to encrypt transmissions from an internal database to an internal server, keeping in mind that the encryption process must add as little latency to the process as possible?

A. ECC
B. RSA
C. SHA
D. 3DES

Answer: D

Explanation:
3DES would be less secure compared to ECC, but 3DES would require less computational power. Triple-DES (3DES) is a technological upgrade of DES. 3DES is still used, even though AES is the preferred choice for government applications. 3DES is considerably harder to break than many other systems, and it’s more secure than DES. It increases the key length to 168 bits (using three 56-bit DES keys).
