Title:
Tate-pairing implementations for tripartite key agreement
Authors: Iwan Duursma, Hyang-Sook Lee
Abstract:We give a closed formula for the Tate-pairing on
the hyperelliptic curve y^2 = x^p - x + d in characteristic p.
This improves recent implementations by Barreto et.al. and
by Galbraith et.al. for the special case p=3.
As an application, we propose a n-round key agreement protocol
for up to 3^n
participants by extending Joux’s pairing-based protocol to
n rounds.
