Group law on a Jacobian for a hyperelliptic curve was proposed by Koblitz in 1989 [27]. It is based on discrete logarithm problem and defined by Jacobian of genus g. It tends to possess qg points, where q denotes the number of elements of Jacobian. The HECC encryption scheme is unconditionally secure under Decisional Diffie–Hellman assumption. Hyperelliptic curves are special class of algebraic curves that are viewed as generalization of elliptic curves. A hyperelliptic curve of genus g = 1 is an elliptic curve. Hyperelliptic curve is given by,
where h(x) is a polynomial of degree ≤ g over a finite field F, f(x) is a monic polynomial of degree 2g + 1 over F
