Summary: In this paper we describe a simple protocol for secure delegation of the elliptic-curve pairing. A computationally limited device (typically a smart-card) will delegate the computation of the pairing \(e(A,B)\) to a more powerful device (for example a PC), in such a way that 1) the powerful device learns nothing about the points \(A\) and \(B\), and 2) the limited device is able to detect when the powerful device is cheating.
