Research Abstract

A pairing inversion formula is considered to be a possible pairing based elliptic curve cryptography specific cryptanalysis. In this research, we gave explicit formulae for the Weil pairing inversion. The result is a dense rational formula and therefore pairing based cryptosystems are not vulnerable to evaluation of the explicit formula. We also constructed pairing friendly hyperelliptic curves from certain pairing non-friendly elliptic curves.
