On a (Flawed) Proposal to Build More Pairing-Friendly Curves

Michael Scott and Paulo S. L. M. Barreto

Abstract: In a recent letter, Cui, Duan and Chan propose a generalisation of the Scott-Barreto method to build a larger family of MNT curves, and they claim that their proposal is also applicable to other curve construction methods. Here we show that the Cui-Duan-Chan technique is irrecoverably flawed.
