With the increase in the use of handheld devices, ECC and HECC have come to the lime light. The size of the cipher-text space is a significant indicator of security level. Unlike the traditional systems, ECC and HECC are defined on the Jacobian of the curves. Counting in the Jacobian is hard. Special methods were devised for counting, but are not yet fast enough. In this thesis, we bring together the Primorial method and the special properties of genus 2 hyperelliptic curves. The resulting method provides an improvement factor of P/j(P), where P is the product of the first p primes and j is Euler's totient function. We will see that the value of p varies, depending on the expected size of the Jacobian.
