Welcome to the resource topic for 2005/116

Title:
On Computable Isomorphisms in Efficient Asymmetric Pairing Based Systems

Authors: Nigel Smart, Frederik Vercauteren

Abstract:

In this paper we examine the hard problems underlying asymmetric pairings, their precise relationships and how they affect a number of existing protocols. Furthermore, we present a new model for the elliptic curve groups used in asymmetric pairings, which allows both an efficient pairing and an efficiently computable isomorphism.
