Matt, a security analyst, needs to select an asymmetric encryption method that allows for the
same level of encryption strength with a lower key length than is typically necessary. Which of the
following encryption methods offers this capability?

A.
Twofish

B.
Diffie-Hellman

C.
ECC

D.
RSA

Explanation:
Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the
algebraic structure of elliptic curves over finite fields. One of the main benefits in comparison with
non-ECC cryptography (with plain Galois fields as a basis) is the same level of security provided
by keys of smaller size.
