Abstract

Since the advent of pairing based cryptography, many researchers have developed several techniques and variants of pairings to optimise the speed of pairing computations. The selection of the elliptic curve for a given pairing based protocol is crucial for operations in the first and second pairing groups of points of the elliptic curve and for many cryptographic schemes. A new variant of superoptimal pairing was proposed in 2023, namely x-superoptimal pairing on curves with odd prime embedding degrees BW13-310 and BW19-286. This paper extends the definition of the x-superoptimal pairing on elliptic curves with even embedding degrees BW10-511 and BW14-351 at 128 bits security level. We provide a suitable formula of the x-superoptimal pairing on BW10-511 and BW14-351 where the Miller loop is about $13.5\%$ and $21.6\%$ faster than the optimal ate pairing on BW10-511 and BW14-351 respectively. The correctness of the x-superoptimal pairing on BW10-511 and BW14-351 and bilinearity has been verified by a Magma code.
