Question

Elliptic curve cryptography is a stronger more efficient cryptography method meant to replace which current encryption technology?

Options

A3DES
BRSA
CDES
DAES

Explanation

Elliptic Curve Cryptography (ECC) is a modern public-key encryption method that offers equivalent security with smaller key sizes and improved efficiency compared to older public-key algorithms. It is specifically designed as a more efficient replacement for the RSA algorithm for public-key operations.

Common mistakes.

A. 3DES is a symmetric-key encryption algorithm, not a public-key algorithm like RSA, and ECC is not a direct replacement for symmetric encryption.
C. DES is an older symmetric-key encryption algorithm, and ECC is not a direct replacement for symmetric encryption.
D. AES is a modern symmetric-key encryption algorithm, and ECC is not a direct replacement for symmetric encryption.
