Which of the following statements is incorrect about elliptic curve cryptography algorithm?

Elliptic curve cryptography algorithm is a public key algorithm.

Key sizes in an elliptic curve cryptography algorithm are in the order of 1024 bits.

Elliptic curve cryptography works with points on a curve.

In elliptic curve cryptography algorithm, elliptic curve is designed by the equation y² = x³ + ax + b.

For generating an elliptic curve public key, algorithm picks a certain point F on the curve and calculates Ap = As*F. Here, A_p is a public key and A_s is a secret key.
