Abstract

See full text

The present disclosure relates to a method and device for performing an elliptic curve cryptography computation comprising: twisting, by a first device based on a first index of quadratic or higher order twist (d), a first point (P′KB) on a first elliptic curve over a further elliptic curve twisted with respect to the first elliptic curve to generate a twisted key (PKB); transmitting the twisted key (PKB) to a further device; receiving, from the further device, a return value (ShS) generated based on the twisted key (PKB); and twisting, by the first device based on the first index of quadratic or higher order twist (d), the return value (ShS) over the first elliptic curve to generate a result (ShS′) of the ECC computation.
