Abstract
Various embodiments of the teachings herein include a method for arranging a shared cryptographic key with a communication partner. The method may include: selecting a first point of a first elliptic curve; sending the first point to the communication partner using a public channel; receiving a second point of the first elliptic curve from the communication partner; and determining the shared key using a non-trivial, inverse shared mapping of the second point with respect to a shared isomorphic mapping of a second elliptic curve onto the first elliptic curve.
