Question

The best way to achieve stronger encryption is to

use or increase the largest possible key space (or key size)

only use block ciphers

use the latest NIST standards for encryption

use hardware accelerated encryption methods.

Answer 1

Use the NIST standards!

Step-by-step explanation:

- A larger key size helps, but it depends what the underlying algorithm is, so this is not in itself a solution.

- Some block ciphers are not strong.

- Hardware acceleration will only produce a result faster, not increase the strength of the encryption.
