Earlier in the decade, they had had a hit with Lee with "I'm a Woman" (1962). Their last major hit production was "Stuck in the Middle
Pairing-based cryptography to an element from a second group. Some researchers classify pairing instantiations into three (or more) basic types: 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. The first group is sometimes referred to as a Gap Group because of the assumed difference in
