If symmetric, pairings can be used to reduce a hard problem in one group to a different, usually easier problem in another group. For example, in groups equipped with a bilinear mapping such as the Weil pairing or Tate pairing, generalizations of the computational Diffie–Hellman problem are believed to be infeasible while the simpler decisional Diffie–Hellman problem can be easily solved using the pairing function.
