The graph in Figure, which depicts the equation y 2 = x3 + ax + b, denotes the: Exhibit:

A.
RSA Factoring problem

B.
Elliptic curve and the elliptic curve discrete logarithm problem

C.
ElGamal discrete logarithm problem

D.
Knapsack problem

Explanation:
The elliptic curve is defined over a finite field comprised of real, complex or rational numbers. The
points on an elliptic curve form a Group under addition. Multiplication (or multiple additions) in an
elliptic curve system is equivalent to modular exponentiation; thus, defining a discreet logarithm
problem.
