Fast explicit formulae for genus 2 hyperelliptic curves using projective coordinates (Updated)

Vladislav Kovtun, Thomas Wollinger

Abstract: This contribution proposes a modification of method of divisors group operation in the Jacobian of hyperelliptic curve over even and odd characteristic fields in projective coordinate. The hyperelliptic curve cryptosystem (HECC), enhances cryptographic security efficiency in e.g. information and telecommunications systems.
