D.
Elliptic Curve Cryptography
Suggested answer: D

Explanation:

Elliptic curve cryptography (ECC)is a more efficient form of public key cryptography as it demands less computational power and offers more security per bit. ECC is based on the mathematical properties of elliptic curves, which are curves that have a special shape that makes them suitable for cryptography. ECC can achieve the same level of security as other public key algorithms with much smaller key sizes, which reduces storage and bandwidth requirements.
